Structural characterization of two solvates of a luminescent copper(II) bis-(pyridine)-substituted benzimidazole complex.

Copper(II) complexes of benzimidazole are known to exhibit biological activity that makes them of inter-est for chemotherapeutic and other pharmaceutical uses. The complex bis-(acetato-κO){5,6-dimethyl-2-(pyridin-2-yl)-1-[(pyridin-2-yl)meth-yl]-1H-benzimidazole-κ2N2,N3}copper(II), has been prepared. The absorption spectrum has features attributed to intra-ligand and ligand-field transitions and the complex exhibits ligand-centered room-temperature luminescence in solution. The aceto-nitrile monosolvate, [Cu(C2H3O2)2(C20H18N4)]·C2H3N (1), and the ethanol hemisolvate, [Cu(C2H3O2)2(C20H18N4)]·0.5C2H6O (2), have been structurally characterized. Compound 2 has two copper(II) complexes in the asymmetric unit. In both 1 and 2, distorted square-planar N2O2 coordination geometries are observed and the Cu-N(Im) bond distance is slightly shorter than the Cu-N(py) bond distance. Inter-molecular π-π inter-actions are found in 1 and 2. A weak C-H⋯π inter-action is observed in 1.

Chemical context

Copper(II) complexes containing n class="Chemical">benzimidazole ligands exhibit anti­cancer properties involving reactive oxygen species and DNA inter­actions (Prosser et al., 2017 ▸; Lewis et al., 2016 ▸; Mal et al., 2014 ▸). Similar complexes show anti­bacterial activity (Chen et al., 2012 ▸). The biological activity suggests that CuII–benzimidazole complexes have potential as chemo­thera­peutic and other pharmaceutical uses.

In addition to biological applications, CuII complexes containing n class="Chemical">benzimidazole have been explored as catalysts. For example, one complex behaves as a ring-opening polymerization catalyst (Zaca et al., 2016 ▸). Others have been used as building blocks for the construction of metal–organic frameworks and coordination polymers (Li et al., 2011 ▸; Machura et al., 2010 ▸).

We recently reported the structures of two zinc(II) complexes of 5,6-dimethyl-2-(n class="Chemical">pyridin-2-yl)-1-[(pyridin-2-yl)meth­yl]-1H-benzimidazole, Me2BzImpy2, that exhibit blue luminescence (DeStefano & Geiger, 2016 ▸) and a luminescent platinum(II) complex that exhibits an inter­molecular anagostic inter­action (DeStefano & Geiger, 2017 ▸). In this report, we expand the series to CuII(Me2BzImpy2)(OAc)2, which is luminescent in solution. Two forms of the compound have been structurally characterized: 1 is an aceto­nitrile solvate and 2 is an ethanol hemisolvate.

Spectroscopy

The absorption and emission spectra of Cu(Me2BzImpy2)(OAc)2 are shown in Fig. 1 ▸. In the UV region, the absorption spectrum is similar to that of the free ligand, n class="Chemical">Me2BzImpy2, (Geiger & DeStefano, 2016 ▸) but red-shifted (λmax = 340 nm, 3.65 eV; ∊ = 17,500 M −1cm−1), as was observed for the zinc(II) (DeStefano & Geiger, 2016 ▸) and platinum(II) (DeStefano & Geiger, 2017 ▸) complexes of Me2BzImpy2. In the previously reported complexes, the bands were assigned as ligand-centered π*←π in nature based on the results of mol­ecular orbital calculations. In addition to the features in the UV region of the spectrum, a ligand-field band is observed in the visible region (λmax = 695 nm, 1.78 eV; ∊ = 77 M −1cm−1). The emission spectrum obtained using an excitation wavelength of 320 nm exhibits a band (λmax = 383 nm, 3.24 eV) similar to those of the ZnII and PtII complexes where there is evidence of involvement of the di­imine in the emissive state (DeStefano & Geiger, 2017 ▸; Hissler et al., 2000 ▸).

Luminescent CuII n class="Chemical">1,10-phenanthroline complexes have been reported (Melnic et al., 2014 ▸; Mistri, García-Granda et al., 2013 ▸; Mistri, Zangrando et al., 2013 ▸). In these complexes, ligand-field transitions appear in the near infrared, which do not exhibit emission bands due to ultrafast non-radiative processes (Melnic et al., 2014 ▸). Bis(1,2-benzenedi­amine-κ2 N,N′)copper(II) nitrate (Supriya & Das, 2003 ▸) and a series of copper(II) complexes with tridentate phenol-substituted picolinylidenes (Das & Pal, 2010 ▸) are other examples of luminescent CuII complexes. However, to our knowledge, Cu(Me2BzImpy2)(OAc)2 is the first luminescent CuII–benz­im­idazole complex reported.

Structural commentary

The two copper complexes explored in this study differ in the co-crystallized solvent: 1 contains one aceto­nitrile mol­en class="Chemical">cule per copper complex, whereas 2 is an ethanol solvate with two symmetry-independent mol­ecules of the copper complex per mol­ecule of ethanol. The two independent mol­ecules will be referred to as 2 and 2 . Representations of the asymmetric units of 1 and 2 along with the respective atom-labeling schemes are found in Figs. 2 ▸ and 3 ▸. The ethanol mol­ecule in 2 is threefold disordered (see Refinement section for details).

In both 1 and 2, the coordination geometries of the copper ions are best described as distorted square planar with monodentate coordination of two n class="Chemical">acetate ligands in addition to the Me2BzImpy2 ligand (see Figs. 2 ▸ and 3 ▸, and Tables 1 ▸ and 2 ▸). In 1, the uncoordinated oxygen atoms are 2.651 (3) and 2.676 (4) Å from the CuII atom. In 2 , the corresponding distances are 2.471 (2) and 2.698 (3) Å; in 2 , the distances are 2.546 (3) and 2.554 (3) Å. The oxygen atoms of the N2O2 coordination sphere have a twist angle from the nitro­gen atoms of 6.7 (2)° for 1. These values are 17.2 (2) and 7.9 (2)° for 2 and 2 , respectively. In 1, 2 and 2 , the two acetate ligands adopt anti conformations.

The Cu—N(n class="Chemical">pyridine) bond distances found in 1 and 2 are slightly longer than the Cu—N(imidazole) bond distances (Tables 1 ▸ and 2 ▸). The bond distances compare favorably with those found in other CuII 2-pyridin-2-yl-1H-benzimidazole complexes. For the four square-planar complexes in the comparison pool (Prosser et al., 2017 ▸; Lewis et al., 2016 ▸; Li et al., 2011 ▸), the Cu—N(pyridine) bond distances are 2.04 (2) Å [range = 2.0047 (2)–2.059 (4) Å] and the Cu—N(imidazole) bond distances are 1.99 (2) Å [range = 1.9645 (2)–2.002 (2) Å].

In 1 and 2, the coordinated pyridine and n class="Chemical">benzimidazole ring systems are approximately coplanar. The torsion angles are reported in Tables 1 ▸ and 2 ▸. In 1 the angle between the mean planes of the benzimidazole ring system and the coordinated pyridine is 0.89 (19)° and in 2 and 2 the corresponding angles are 3.5 (2) and 4.91 (16)°, respectively.

Supra­molecular features

There are several types of hydrogen-bonding inter­actions present in 1, as seen in Table 3 ▸. The aceto­nitrile solvate participates as acceptor in C—H⋯N n class="Chemical">hydrogen bonds in which an aromatic hydrogen atom (H9) is donor. Additionally, C—H⋯O hydrogen bonds involving the uncoordinated acetate oxygen atom O2 as acceptor and the aromatic carbon atoms C10 and C16 as donors result in chains that run parallel to [ 10] (Fig. 4 ▸). In 2, the most significant hydrogen-bonding inter­actions (Table 4 ▸) involve the disordered ethanol solvate mol­ecule, which participates as donor in O—H⋯O hydrogen bonding with the uncoordinated acetate oxygen atoms O2 and O6 as acceptors.

In addition to weak C—H⋯O and C—H⋯N hydrogen bonds (Table 3 ▸), the extended structure of 1 exhibits inter­molen class="Chemical">cular C—H⋯π and π–π inter­actions (see Tables 3 ▸ and 5 ▸). Fig. 5 ▸ shows a partial packing diagram emaphasizing these inter­actions. The closest π–π inter­action exists between the coordinated pyridine rings of mol­ecules related by a crystallographically imposed inversion center. Weaker π–π inter­actions exist between imidazole rings and between coordin­ated pyridine rings and benzene rings on inversion-related mol­ecules. The C—H⋯π inter­action is between inversion-related mol­ecules and involves the benzene ring and a hydrogen atom of the 1-(pyridin-2-yl)methyl substituent.

No significant C—H⋯π inter­actions are observed in 2; however, a number of close π–π inter­actions exist (see Table 5 ▸ and Fig. 6 ▸). A π–π inter­action between 2 and 2 involves the 1-(pyridin-2-yl)methyl substituent of each mol­en class="Chemical">cule. In both 2 and 2 , the closest π–π inter­action is between imidazole rings related by the crystallographically imposed inversion center. The Cg(Im)⋯Cg(Im) separation in 2a is shorter than that observed in 2b.

π stacking is prevalent in CuII n class="Chemical">1,10-phenanthroline complexes (Melnic et al., 2014 ▸) and it has been suggested as a necessary structural feature for the DNA-cleavage activity exhibited by these and similar complexes (McCann et al., 2013 ▸). π stacking has also been implicated in the fluorescence quenching of amyloid-β peptide, which could be of relevance to possible therapeutic applications of CuII chelators in the treatment of Alzheimer’s disease (Melnic et al., 2014 ▸).

Database survey

A search of the Cambridge Structural Database (WebCSD; Groom et al., 2016 ▸) for 2-(pyridin-2-yl)-1H-benzimidazole ligands coordinated to n class="Chemical">CuII yielded 14 different compounds. The most similar to 1 and 2 are the four which adopt square-planar coordination geometries (EQOGAT: Li et al., 2011 ▸; MALLAP: Lewis et al., 2016 ▸; CANMIQ and CANMUC: Prosser et al., 2017 ▸). Two complexes exhibit octa­hedral coordination geometries (MALLUJ: Lewis et al., 2016 ▸; TUBXUK: Altaf & Stoeckli-Evans, 2009 ▸), five have square-pyramidal geometries (RAXQUE: Chen et al., 2012 ▸; BUYCUU: Machura et al., 2010 ▸; ZOTCUI: Mal et al., 2014 ▸; GUXBOR: Zhang & Yang, 2010 ▸; COXSOY01: Altaf & Stoeckli-Evans, 2009 ▸), and three have trigonal–bipyramidal geometries (CANMEM and CANMOW: Prosser et al., 2017 ▸; OVAXEQ: Zaca et al., 2016 ▸). Excluding those complexes exhibiting Jahn–Teller distorted geometries, the average Cu—N(pyridine) and Cu—N(imidazole) bond distances found are 2.04 (2) and 2.00 (4) Å, respectively.

Synthesis and crystallization

5,6-Dimethyl-2-(pyridin-2-yl)-1-[(n class="Chemical">pyridin-2-yl)meth­yl]-1H-benzimidazole, Me2BzImpy2, was prepared as previously described (Geiger & DeStefano, 2014 ▸). Solvents were of commercial analytical grade and used without further purification. Spectroscopic measurements were performed at ambient temperature. Absorption spectra were recorded on a Varian Cary 50 Bio UV–Visible spectrophotometer. Excitation and emission spectra were recorded on a Photon Technology Inter­national Inc. QM-40 spectrofluorimeter using an excitation wavelength of 320 nm.

Bis(acetato-κO){5,6-dimethyl-2-(pyridin-2-yl)-1-[n class="Chemical">pyridin-2-yl)meth­yl]-1H-benzimidazole-κ2 N 2,N 3}copper(II), Cu(Me2BzImpy2)(OAc)2, was prepared by refluxing 200 mg (0.63 mmol) Me2BzImpy2 and 130 mg (0.65 mmol) copper acetate monohydrate in 15 mL ethanol for 10 min. The ethanol was reduced in volume until crystallization commenced. After chilling in an ice bath, the blue crystalline product was separated by filtration. The yield was 0.24 g (0.52 mmol, 83% yield). Single crystals of 1 and 2 were obtained by slow evaporation of aceto­nitrile and ethanol solutions of Cu(Me2BzImpy2)(OAc)2, respectively.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 6 ▸. Early in the refinement of 2, the ethanol hemisolvate mol­en class="Chemical">cule was found to be disordered. The disorder was modeled using three contributors. Successful refinement required the use of O—H, C—C and C—O distance restraints of 0.84, 1.53 and 1.43 Å, respectively, and restraints on the U components of the anisotropically refined atoms in the disordered ethanol mol­ecule. The disorder model refined to occupancies of 0.411 (3):0.362 (3):0.227 (3). All H atoms were located in difference-Fourier maps for 1 and 2, except those associated with the disordered ethanol mol­ecule. H atoms bonded to C atoms were refined using a riding model, with C—H = 0.95 Å and U iso(H) = 1.2U eq(C) for the aromatic positions; C—H = 0.99 Å and U iso(H) = 1.2U eq(C) for the methyl­ene groups; and C—H = 0.98 Å and U iso(H) = 1.5U eq(C) for the methyl groups. The hy­droxy H atoms in the disordered ethanol contributors were refined using a rotating-group model with C—O—H tetra­hedral, distance restraints to acceptor atoms (O6 and symmetry-generated O2) and with U iso(H) = 1.5U eq(O).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. All H atoms were located in difference Fourier maps. H atoms bonded to C atoms were refined using a riding model, with C–H = 0.95 Å and Uiso(H) = 1.2Ueq(C) for the aromatic positions; C–H = 0.99 Å and Uiso(H) = 1.2Ueq(C) for the methylene group; and C–H = 0.98 Å and Uiso(H) = 1.5Ueq(C) for the methyl groups.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Crystal data, data collection and structure refinement details are summarized in Table 1. Early in the refinement of (2), the ethanol hemisolvate molecule was found to be disordered. The disorder was modeled using three contributors. Successful refinement required the use of O–H, C–C and C–O distance restraints of 0.84 Å, 1.53 Å and 1.43 Å, respectively, and restraints on the Uij components of the anisotropically refined atoms in the disordered ethanol. The disorder model refined to occupancies of 0.411 (3) : 0.362 (3) : 0.227 (3). All H atoms were located in difference Fourier maps, except those associated with the disordered ethanol molecule. H atoms bonded to C atoms were refined using a riding model, with C–H = 0.95 Å and Uiso(H) = 1.2Ueq(C) for the aromatic positions; C–H = 0.99 Å and Uiso(H) = 1.2Ueq(C) for the methylene groups; and C–H = 0.98 Å and Uiso(H) = 1.5Ueq(C) for the methyl groups. The hydroxy H atoms in the disordered ethanol contributors were refined using a rotating group model with C–O–H tetrahedral, distance restraints to acceptor atoms (O6 and symmetry-generated O2) and with Uiso(H) = 1.5Ueq(O).
