Crystal structure of bis-(2,2'-bi-pyridine)[N'-(quino-lin-2-ylmethylidene)pyridine-2-carbohydrazide]ruthenium(II) bis(tetra-fluorido-borate) di-chloro-methane tris-olvate.

The title compound, [Ru(C10H8N2)2(C16H12N4O)](BF4)2·3CH2Cl2, crystallizes with one complex dication, two BF4 (-) counter-anions and three di-chloro-methane solvent mol-ecules in the asymmetric unit. The central Ru(II) atom adopts a distorted octa-hedral coordination sphere with two 2,2'-bi-pyridine (bpy) and one quinoline-2-carbaldehyde (pyridine-2-carbon-yl)hydrazone (HL) ligand. The hydrazone ligand has a Z form and coordinates to the Ru(II) atom via the amide-O and imine-N atoms, affording a planar five-membered chelate ring, while its pyridine-N and quinoline-N donor atoms in the substituents are non-coordinating. The hydrazone N-H group forms an intra-molecular hydrogen bond with the quinoline-N atom. In the crystal, the quinoline moiety of HL shows the shortest π-π stacking inter-action with the pyridine substituent of HL in a neighbouring complex, the centroid-to-centroid distance being 3.793 (3) Å.

Chemical context

Aroylhydrazones, ArC(O)NHN=CHR, are easily prepared by the reaction of an aroylhydrazine [ArC(O)NHNH2] with an aldehyde (RCHO), and they can coordinate to a metal atom via the amide-O and imine-N atoms (Bernhardt et al., 2007 ▸; Raveendran & Pal, 2005 ▸, 2006 ▸). These hydrazones are often obtained as a mixture of E and Z isomers (Su & Aprahamian, 2014 ▸), and both isomers are generally weak acids. However, when they coordinate to a metal ion through the imine-N atom, their acidity becomes higher (Chang et al., 2010 ▸), and the deprotonated hydrazonato complexes are often isolated (Nonoyama, 1974 ▸). For example, the reaction of cis-[RuCl2(bpy)2] (bpy is 2,2′-bi­pyridine) and a series of aroylhydrazones in the presence of tri­ethyl­amine afforded the cationic complexes [RuII(bpy)2(hydrazonato)](ClO4 or PF6), which were unambiguously characterized by X-ray analysis (Duan et al., 1998 ▸; Ghosh et al., 2014 ▸).

In the current study we utilized a 2-picolinoylhydrazone (Ar = 2-C5H4N) with a 2-quinolyl substituent on the imine-C atom (R = 2-C9H6N). This compound (HL) has several possible coordination modes because of the additional pyridine and quinoline ligating groups. In a previous study we investigated the reaction products from [RuCl2(PPh3)3] and (an E/Z mixture of) HL under several reaction conditions, and characterized three geometrical isomers of [RuCl2(PPh3)2{HL-κO(amide),κN(imine)}] as well as a linkage isomer of trans(P)-[RuCl2(PPh3)2{HL-κN(imine), κN(quinoline)}] (Mori et al., 2014 ▸). Here, we have examined the reaction of the Z isomer of HL and an RuII(bpy)2 precursor prepared from cis-[RuCl2(bpy)2] and AgBF4 (2 eq.) in ethanol. The resulting orange product had the composition Ru(bpy)2(HL)(BF4)2, indicating the formation of an RuII complex with a neutral hydrazone ligand, in contrast to the previous examples of [RuII(bpy)2(hydrazonato)](ClO4 or PF6). Therefore, in order to determine the mol­ecular and crystal structure of the present product, an orange prismatic crystal of the title compound, (I), [Ru(C10H8N2)2(C16H12N4O)](BF4)2·3CH2Cl2, was analysed by X-ray diffraction.

Structural commentary

The asymmetric unit of compound (I) contains one complex dication (Fig. 1 ▸), two BF4 − counter-anions and three di­chloro­methane solvent mol­ecules. In the cationic complex, the neutral hydrazone is present as its Z isomer and coordinates to the RuII atom through the amide-O and imine-N atoms, forming a virtually planar five-membered chelate ring [maximum deviation from the least-squares plane = 0.015 (4) Å], as well as two bidentate bpy co-ligands. An intra­molecular hydrogen bond between the hydrazone N—H group and the quinoline-N atom is observed (Table 1 ▸). The pyridine (py) and quinoline (qn) moieties of HL are non-coordinating, but their mean planes are almost co-planar to the RuII carb­oxy­lic acid hydrazide (CAH: —C(O)NHN=) chelating plane. The dihedral angles between these planes are: py vs CAH = 5.4 (2), qn vs CAH = 3.7 (2) and py vs qn = 2.3 (2)°.

The Ru1—O1(amide) and Ru1—N2(imine) bond lengths in (I) are 2.090 (3) and 2.047 (4) Å, respectively, which are comparable to those in [Ru(bpy)2{3-py-C(O)NN=CHC6H4(4-NMe2)}]ClO4 [2.083 (1) and 2.040 (1) Å, respectively; Duan et al., 1998 ▸] and [Ru(bpy)2{2-C6H4(OH)–C(O)NN=CH-2-fur­yl}]PF6 [2.072 (2) and 2.089 (1) Å, respectively; Ghosh et al., 2014 ▸]. The bite angle of the hydrazone chelate, O1—Ru—N2, in (I) is 77.8 (1)°, which is also similar to the above-mentioned hydrazonato complexes, 78.0 (1) and 78.6 (1)°, respectively. Thus, the substituent groups on the carbonyl-C and the imine-C atoms of the aroylhydrazones, as well as the protonation (or deprotonation) states of the hydrazone N—H moiety, do not significantly affect the structural parameters of the RuII—(hydrazone/hydrazonate) coordination bonds.

Supra­molecular features

In the crystal structure of (I) there are no remarkable hydrogen-bonding inter­actions between the cationic complex, BF4 − anions and the solvated di­chloro­methane mol­ecules. However, each of the planar HL and two bpy ligands in the complex cation shows a π–π stacking inter­action with the respective neighbouring complexes (Fig. 2 ▸). The quinoline plane (N1/C1–C9) has a stacking inter­action with the pyridine plane (N4i/C12i–C16i) of HL in a neighbouring complex [symmetry code: (i) –x, –y + 1, –z + 2]; the shortest C⋯C distance between these rings is C6⋯C16i = 3.444 (8) Å and the centroid-to-centroid distance between the planes C1–C6 and N4i/C12i–C16i is 3.793 (3) Å. One of the bpy ligands, N5/C17–C26/N6, is stacked with the same symmetry-related ligand, N5ii/C17ii–C26ii/N6ii, in a neighbouring complex [symmetry code: (ii) –x, –y + 1, –z + 1]; the shortest C⋯C distance between them is C20⋯C25i = 3.373 (8) Å, and the centroid-to-centroid distance between the N6/C22–C26 and N6ii/C22ii–C26ii planes is 3.864 (3) Å. For the other bpy ligand, N7/C27–C36/N8, a similar inter­action is observed, and the shortest C⋯C distance between them is C32⋯C35iii = 3.509 (8) Å and the centroid-to-centroid distance between planes N8/C32–C36 and N8iii/C32iii–C36iii is 3.918 (3) Å [symmetry code: (iii) –x, –y, –z + 1]. Considering these stacking inter­actions, the complex cations are arranged in a three-dimensional extended structure in the crystal.

Database survey

Four geometrical and linkage isomers of [RuCl2(PPh3)2(HL)] with the same picolinoylhydrazone ligand, HL, have been reported previously (Mori et al., 2014 ▸). There is no record of any [RuII(bpy)2(carbonyl­hydrazone)]2+ complexes with its protonated (neutral) hydrazone form in the CSD database (Version 5.35, last update May 2014; Groom & Allen, 2014 ▸). The deprotonated (anionic) hydrazonate analogues, [Ru(bpy)2{3-py-C(O)NN=CHC6H4(4-NMe2)}]ClO4 (Duan et al., 1998 ▸) and [Ru(bpy)2{2-C6H4(OH)–C(O)NN=CH-2-fur­yl}]PF6 as well as the thio­phene analogue have been reported (Ghosh et al., 2014 ▸). The structurally related compound [RuII(bpy)2{C6H5C(O)NNC6H5}]PF6 with a monoanionic (radical) ligand has also been reported (Ehret et al., 2012 ▸).

Synthesis and crystallization

All reagents and solvents were commercially available and used without further purification. The starting ruthenium(II) complex, cis-[RuCl2(bpy)2]·2H2O (Sullivan et al., 1978 ▸), and hydrazone ligand, Z-HL (Mori et al., 2014 ▸), were prepared according to literature procedures. A mixture of cis-[RuCl2(bpy)2]·2H2O (618 mg, 1.19 mmol) and AgBF4 (463 mg, 2.38 mmol) in ethanol (80 ml) was stirred in the dark at room temperature overnight. The resulting white precipitate (AgCl) was filtered off, and Z-HL (328 mg, 1.19 mmol) was added to the filtrate. The mixture was heated to reflux for 9 h and then cooled to room temperature. The solution was concentrated to ca. 10 ml under reduced pressure, and the resulting microcrystalline powder was collected by filtration and dried in air. Yield: 869 mg (81%). Analysis calculated for C36H28B2F8N8ORu·2H2O: C 48.08, H 3.59, N 12.46%. Found: C 48.11, H 3.42, N 12.18%. Orange prismatic crystals of (I) suitable for X-ray analysis were obtained by diffusion of layered hexane into a di­chloro­methane solution.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The position of the hydrazone (N—)H atom was located in a difference Fourier map and refined with U iso = 1.2U eq(N). All other H atoms were refined using a riding model, with C—H = 0.95 (aromatic) or 0.99 (methyl­ene) Å and U iso = 1.2U eq(C).

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