Crystal structure of (2,2'-bipyrid-yl)[2,6-bis-(1-butyl-1H-benzimidazol-2-yl)pyridine]-chlorido-iridium(III) tri-fluoro-methane-sulfonate.

The title complex compound, [Ir(C27H29N5)Cl(C10H8N2)](CF3SO3)2, was synthesized for a study of iridium(III)/periodate redox systems in water. The coordination geometry of the complex can be best described as distorted octa-hedral, with an r.m.s. deviation of 8.8 (8)% from ideal octa-hedral rectangular geometry. In the crystal, C-H⋯O and C-H⋯F inter-actions between the complex cation and the tri-fluoro-methane-sulfonate anions are observed, as well as a C-H⋯Cl inter-molecular inter-action between neighboring complex cations. In addition, the benzimidazole ring systems display parallel-displaced π-π stacking with centroid-centroid distances of 3.585 (3)-3.907 (3) Å. One of the two tri-fluoro-methane-sulfonate anions is disordered over two orientations with an occupancy ratio of 0.582 (6):0.418 (6). The title complex was characterized using FT-IR, cyclic voltammetry/rotating disc electrode polarography, fluorescence spectrometry, high resolution mass spectrometry, CHN elemental analysis and 1H NMR spectroscopy.

Chemical context

Some iridium(III) complexes, specifically those containing di­hydroxy­bipyridine ligands, have been shown to catalyze the oxidation of water in the presence of periodate (IO4 −) as the sacrificial oxidant (DePasquale et al., 2013 ▸; Lewandowska-Andralojc et al., 2014 ▸). The title complex was synthesized within a project exploring the nature of iridium(III)/periodate systems in water. The ligands, 2,6-bis­(N-butyl­benzimidazol-2′-yl)pyridine (bubzimpy) and 2,2′-bi­pyridine (bipy), were chosen for their denticity characteristics, available donor atoms and solubility characteristics.

Structural commentary

The cationic complex of the title salt is composed of one mol­ecule each of bipy and bubzimpy, and a chloride ion coordinating to the iridium(III) atom, with charge balance provided by two crystallographically independent tri­fluoro­methane­sulfonate ions (Fig. 1 ▸). The bond lengths and angles are comparable to similar complexes (Yutaka et al., 2005 ▸), though the torsion angles show distinct differences. The bond angles involving Ir range from 79.55 (12)° (N6—Ir—N7) to 178.09 (13)° (N3—Ir—N7), with the bond lengths between 1.992 (3) Å (Ir—N3) and 2.3510 (9) Å (Ir—Cl). The Ir complex with 2,6-bis­(N-methyl­benzimidazol-2′-yl)pyridine (mebzimpy) and bipy synthesized by Yutaka et al. (2005 ▸) is closely related to the title complex. Selected bond lengths, bond angles and torsion angles from their complex are compared with those of the title complex in Table 1 ▸. The torsion angle N1—C7—C8—N3 [−6.6 (5)°] for one of the benzimidazoles indicate that the benzimidazole is further removed from coplanarity with the central pyridine plane than it is in the mebzimpy analogue. Meanwhile, the two halves of the coordinating bipy mol­ecule are slightly more rotated vs one another than in the mebzimpy analogue, as indicated by the N6—C32—C33—N7 torsion angle of 7.3 (5)°. The dihedral angle between the mean planes of the bubzimpy and bipy ligands is 89.32 (6)°. The r.m.s. angular deviation from ideal octa­hedral rectangularity, defined as 0.312[Σ(θ − 90)2]1/2 where θ are the twelve cis-angles in the pseudo-octa­hedron (Popovitch et al., 2012 ▸), is 8.8 (8)% for the title complex, which is comparable to the value of 7.9 (7)% in the analogous N-methyl­ated complex. One of the two tri­fluoro­methane­sulfonate anions in the title complex is disordered over two orientations around the C—S bond with an occupancy ratio of 0.582 (6):0.418 (6).

Supra­molecular features

The mol­ecules stack in the crystal so that the benzimidazole ring systems of neighbouring mol­ecules are parallel to each other, enabling π–π inter­actions to occur. The centroid–centroid distances and the slippages of the slipped π–π stacking inter­actions are given in Table 2 ▸. The shortest inter­planar distance is 3.337 (6) Å with the two π–π stacked benzene rings slipped by 2.033 (8) Å. These inter­actions link the mol­ecules into a staircase structure along [011] as shown in Figs. 2 ▸ and 3 ▸. The slipped π–π stacking arrangement (Fig. 3 ▸) suggests that isomorphous replacement of iridium(III) mol­ecules by non-luminescent/non-quenching analogues could lead to the formation of a superantenna system (Mikhalyova et al., 2015 ▸). The two distinct tri­fluoro­methane­sulfonate anions balance the complex charge and display C—H⋯O and C—H⋯F hydrogen bonds (Table 3 ▸). These inter­actions involve the O and F atoms from the anions inter­acting with the CH units from bipy as well as the pyridine ring of bubzimpy. An inter­molecular C—H⋯Cl inter­action is also observed between the coordinating chloride ion and the benzimidazole ring of bubzimpy on the neighboring complex (Table 3 ▸). Although this inter­action is weaker than the prominent C—H⋯O inter­actions, it contributes to the overall orientation of the packing in the crystal.

Electrochemistry

The redox chemistry of the IrIII complex was studied using cyclic voltammetry (CV) and rotating disc electrode (RDE) polarography, which were performed at 298 K on 0.3 mM Ir complex in aceto­nitrile with 0.1 M tetra­butyl­ammonium hexa­fluorido­phosphate (TBAPF6) as the supporting electrolyte, at scan rates ranging from 50 to 800 mV s−1 for CV, and 1200 and 2400 rpm for the RDE. Experiments were run on a BASi-Epsilon instrument using a three-electrode cell, a non-aqueous reference electrode (APE) (Pavlishchuk & Addison, 2000 ▸) and a 3 mm diameter Pt disc working electrode. No well-defined anodic process is observed below +1400 mV, indicating that the oxidative potential for the Ir complex is higher than the potential window available in our experiments. The cathodic electrochemistry is not straightforward; however, there are three reductive processes with cathodic peak potentials of −1211, −1472 and −1719 mV. Similar results have been reported for the mebzimpy complex (Yutaka et al., 2005 ▸). In the RDE polarogram, a reductive wave was seen at E 1/2 = −1042±5 mV, from which the diffusion coefficient of the mol­ecule is estimated to be D = 9.0×10−6 cm2 s−1 in MeCN, corresponding to a Dη value of 3.3×10 −8 g cm s−2, consistent with a one-electron transfer.

UV–Vis and Fluorimetry

The photochemical and photophysical properties of iridium(III) complexes have been studied extensively in the last few decades in order to better understand their potential for applications in areas like solar energy and electroluminescence (EL) devices (Nazeeruddin et al., 2003 ▸ ). The optical absorption spectrum of the title complex is displayed in Fig. 4 ▸. In such mixed-ligand complexes, ligand π–π* transition bands typically overlap; however, the ligand π–π* bands for bipy and bubzimpy in our complex were well-resolved at 315 and 352 nm, respectively, similarly to those observed by Yutaka et al. (2005 ▸). As has often been observed in compounds of this type (Yutaka et al., 2005 ▸), there is a strong emission in the yellow region of the spectrum with the intensity peaking at 542 nm (Fig. 5 ▸). The excitation profile is dominated by an absorption maximizing at 302 nm, corresponding closely to the bipy π–π* transition at 315 nm.

Database survey

Crystal structures of complexes containing bubzimpy as a ligand exist in the literature. This ligand chelates well to other transition metals, such as ruthenium (Yu et al., 2012 ▸), copper (Kose et al., 2014 ▸), gadolinium, lanthanum (Drew et al., 2004 ▸) and manganese (Kose & McKee, 2014 ▸). Hijazi et al. (2010 ▸) reported a platinum complex with a ligand similar to bubzimpy, 2,6-di(N-hexyl­benzimidazol-2′-yl)pyridine. Similarly, Mathew & Sun (2010 ▸) showed a variety of 2,6-bis­(N-alkyl­benzimidazol-2′-y)pyridine platinum(II) complexes with one coordinating chloride as in our iridium complex. These platinum complexes involved variation of the alkyl chain on the benzimidazole ligand, as well as varied counter-ions, such as PF6 −, ClO4 −, and BF4 −.

Synthesis and crystallization

The bubzimpy ligand used was prepared using a previously reported alkyl­ation method (Nozari et al., 2014 ▸). The title complex was synthesized following a method adapted from the literature (Yutaka et al., 2005 ▸). Sodium hexa­chlorido­iridate(IV) (0.28 g, 0.5 mmol) was reduced to hexa­chlorido­iridate(III) with ascorbic acid under a nitro­gen atmosphere. The reduced iridium and the bubzimpy (0.36 g, 0.5 mmol) were dissolved in warm ethyl­ene glycol (5 mL) and then heated on a steam bath for 4 h, after which the reddish brown solid was filtered off and washed with ether and chloro­form (Fig. 6 ▸). This resulting trichlorido-inter­mediate [0.057 g, 78 mmol; FAB-LSIMS MS: calculated (m+) m/z 721.110, found 721.135] was then dissolved in hot ethyl­ene glycol (10 mL) with 2,2′-bi­pyridine (0.015 g, 94 mmol) and stirred at 433 K for 18 h (Fig. 7 ▸). The resulting iridium complex was precipitated by addition of aqueous sodium tri­fluoro­methane­sulfonate and then filtered off and washed with ether and chloro­form. The crude product was purified via a two month diffusion of toluene into a methyl­ene chloride solution, yielding orange crystals. M.p. > 523 K; Analysis calculated: C 42.3, H 3.35, N 8.86; found: C 42.7, H 3.70, N 9.06; 1H NMR (500 MHz, C2D6OS): δ 10.1 (d, 1H), 9.20 (d, 1H), 8.90 (d, 1H), 8.82 (d, 1H), 8.75–8.67(t, 2H), 8.43 (t, 1H),8.13 (m, 1H), 8.07 (m, 1H), 7.94 (m, 2H), 7.72 (t, 1H), 7.59 (m, 2H), 7.49 (t, 1H), 7.30 (m, 2H), 5.90 (m, 2H), 3.41 (m, 4H), 1.95 (m, 4H), 1.49–1.35 (m, 4H), 0.99–0.74 (m, 6H); FT–IR: 3085, 2959, 2873, 1606, 1466, 1451, 1154, 844, 745 cm−1; FAB MS: calculated (m-CF3SO3)+ m/z 956.195, found 956.198.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 4 ▸. H atoms were positioned geometrically and constrained to ride on their parent atoms, with C—H bond lengths of 0.95, 0.99 and 0.98 Å for aromatic CH, aliphatic CH2 and CH3 groups, respectively. Methyl H atoms were allowed to rotate but not to tip to best fit the experimental electron density. U iso(H) values were set to a multiple of U eq(C) with 1.5 for CH3 and 1.2 for CH and CH2 units.

One of the two tri­fluoro­methane­sulfonate anions was refined as disordered over two orientations [occupancy ratio 0.582 (6):0.418 (6)]. The two components were restrained to have geometries similar to that of the non-disordered anion (SAME with esd 0.02 Å), and the disordered atoms were subjected to a rigid-bond restraint (RIGU with esd 0.001 Å2). Reflections 001 and 10 affected by the beam stop were omitted from the refinement. The residual electron density peaks of 3.18 and 3.12 e Å−3 are located 0.89 and 0.85 Å, respectively, from atom Ir.

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. One of the two triflate anions is disordered with two alternative orientations. The two moieties were restrained to geometries similar to that of the not disordered anion, and disordered atoms were subjected to a rigid bond restraint (RIGU in Shelxl). Reflections 0 0 1 and -1 1 0 were affected by the beam stop and were omitted from the refinement.
