(Received 24 November 2008; accepted 11 December 2008; online 20 December 2008)

A new ruthenium complex, [RuBrCl(C28H32N2)], has been synthesized and characterized by elemental analysis, 1H NMR, 13C NMR, IR-spectroscopy and a single-crystal X-ray diffraction study. The Ru atom in this complex is best described as having a considerably distorted octa­hedral coordination environment with the arene occupying three coordination sites. Two further coordination sites are occupied by chloride and bromide ligands, while the sixth site is occupied by the carbene. The carbene portion of the ligand is a benzimidazole ring. This ring is connected to the C6H4C(CH3)3 arene by a CH2 bridge. This leads to a system with very little apparent strain. The two halogen atoms are disordered between Br and Cl. Two partial Cl atoms share the same sites as two partial Br atoms so that the title compound effectively has one Cl and one Br atom. C—H⋯X (X = Cl, Br) hydrogen bonds help to stabilize the crystal structure.

N-Heterocyclic carbenes have received great attention since the first synthesis of a carbene compound,1,3-di-l-adamantylimidazol-2-ylidene, by Arduengo et al., (1991). N-heterocyclic carbenes generally derived from imidazolium, tetrahydropyrimidin-1-ium and benzimidazolium salts, have attracted wide spread attention as ligands for main group elements and transition metals. The N-heterocyclic carbene metal complexes are remarkably stable toward heat, air, and moisture, and many organic reactions using these complexes as catalysts have been investigated. These include Suzuki-Miyura, Sonogashira, Stille and Heck reactions (Herrmann et al., 1995; Herrmann, 2002; Navarro et al., 2006; Arduengo & Krafczyc,1998).

Previous work from our research groups in this area has focused on the elaboration of olefins as electron-rich heterocyclic carbene precursors to allow the formation of chelating carbenes. We have also looked at the rapidly developing chemistry of η6-arene ruthenium(II) complexes containing substituted imidazolidin-2-ylidenes (Özdemir et al., 2001; Çetinkaya et al., 2001, 2002, 2003), and on synthesis, characterization, crystal structure, and using palladium, platinum and ruthenium N-heterocyclic carbene complexes as catalysts (Yaşar et al., 2008; Arslan et al., 2007a, 2007b, 2007c, 2004a, 2004b, 2005a, 2005b).

In the present study, we have synthesized and characterized a new ruthenium complex, (1-(4-tert-butylbenzyl)-3-(2,4,6-trimethylbenzyl)-benzimidazol-2-ylidene)ruthenium(II) bromide chloride, (I). The molecular structure of the title compound, (I), is depicted in Fig. 1.

The carbene portion of the ligand is a benzimidazole ring. This ring is connected to the C6H4C(CH3)3 arene by a CH2 bridge. This leads to a system with very little apparent strain. The ruthenium atom in the title compound is best described as having an octahedral coordination environment, with the arene occupying three coordination sites. Two further coordination sites are occupied by Cl and Br ligands, while the sixth site is occupied by the carbene carbon of benzimidazole ring. The ruthenium atom is situated 1.658 (5) Å from the ring centroid of the arene atom. While there are substantial differences in the C—C and C—Ru distances for the arene ring, there is no evidence of the alternating C—C bonds observed in some ruthenium-arene complexes (Begley et al., 1991). The arene ring is essentially planar, the mean deviation from the plane being 0.013 (12) Å. In addition, the trimethylbenzyl and benzimidazole rings are almost planar with the maximum deviations of 0.009 (12) Å for atom C25 and, 0.003 (11) Å for atom C2. The benzimidazole moiety is planar and it forms dihedral angles of 87.16 (6)° and 85.31 (7)°, respectively, with the mean planes through the arene and trimethylbenzyl rings.

The two halogen atoms are disordered between Br and Cl. Two chlorine atoms share the same site as two bromine atoms so that the title compound effectively has one Cl and one Br atom. The occupancies of the Cl1 and Cl2 atoms are 0.399 (11) and 0.630 (11), respectively, and those of the Br1 and Br2 atoms are 0.601 (11) and 0.370 (11), respectively.

The structure of the title compound is assembled by intermolecular C—H···Cl hydrogen bonds, to form a two-dimensional framework (Fig. 2, 3 and Table 1) (Macrae et al., 2006). The intermolecular contacts, C—H···Br, are also listed in Table 1.

All reactions for the preparation of (I) and (II) were carried out under Ar in flame-dried glass-ware using standard Schlenk-type flasks. The solvents used were purified by distillation over the drying agents indicated and were transferred under Ar: CH2Cl2 (P4O10), hexane, toluene (Na). RuClBr[η1-CN{CH2(η6-C6H4CMe3-4)}C6H4N(CH2C6H2Me3-2,4,6)]: A suspension of 1-(4-terbutylbenzyl)-3-(2,4,6-trimethylbenzyl)benzimidazolium bromide (1.00 g, 2.10 mmol), Cs2CO3 (0.7 g, 2.14 mmol), [RuCl2(p-cymene)]2 (0.5 g, 0.82 mmol) and molecular sieves was heated under reflux in degassed dry toluene (20 ml) for 12 h. The reaction mixture was then filtered while hot, and the volume was reduced to about 10 ml before addition of n-hexane (10 ml). The precipitate formed was crystallized from CH2Cl2/hexane (5:10 ml) to give the crystal product (Fig. 3). Yield 1.00 g (82%). M.p.: 339–340 oC. FT—IR (KBr pellet, cm-1): νCN 1432 cm-1. Anal.

Special details top

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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
