3-(bromomethyl)benzonitrile (11 mmol) was added to 2-mercaptobenzimidazole (10 mmol) in dry ethanol (25 ml). The mixture was refluxed for 24 h. The reaction mixture was diluted with ethyl acetate (100 ml), and the resulting solid was collected and dissolved in 20 ml of water. 40 ml of a solution of sodium hydrogen carbonate (35 g in 100 ml of water) was added. A white powder was isolated by filtration and dried to give the title compound. Colourless crystals of the title compound suitble for X-ray diffraction were from a solution of 50 mg in 20 ml methanol after 7 d.
All H atoms were fixed geometrically and treated as riding with C—H = 0.93 Å (aromatic), 0.97 Å (methylene) or 0.96 Å (methyl) with Uiso(H) = 1.2Ueq(Caromatic, Cmethylene)

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. |

It is well known that Benzimidazole and its derivatives have received much attention due to their versatile pharmacological activities (Negwer & Scharnow, 2001). To further investigate the influence of the bridging ligand on the formation of supramolecular complexes, we designed and prepared a Benzimidazole-containing ligand, and used the ligand to generate some coordination polymers with interesting topologies. Here, we reported the crystal structure of the title compound. The molecular structure of the title compound, C15H11N3S, and the atomic labeling scheme are shown in Fig. 1. In this Structure, the nine-membered benzimidazole ring system C1/N1/C2/C3/C4/C5/C6/C7/N2 is essentially planar. The phenyl ring C9/C10–C14 is connected to the benzimidazole ring system by the SCH2 group. The bond lengths and angles have normal values, the dihedral angle between the benzimidazole ring system and the phenyl substituent is 51.77 (22)°, and the molecules are linked by intermolecular N—H···N hydrogen bonds which leads to the formation chains C(4) along the [001] direction (Bernstein et al., 1995).
