Bis[1-benzyl-2-(1,3-thia­zol-4-yl)-1H-benzimidazole-κ²N²,N³]dichloridocobalt(II)

In the title compound, [CoCl₂(C₁₇H₁₃N₃S)₂], the Co^II atom exhibits a distorted octa­hedral coordination geometry involving two chloride ligands, one of which is split over two positions [refined site-occupancy ratio = 0.847 (18):0.153 (18)], and four N-atom donors from two 1-benzyl-2-(1,3-thia­zol-4-yl)-1H-benzimidazole ligands. The two chelate rings including the Co^II atom are essentially planar, the maximum deviations from the mean planes being 0.080 (2) and 0.046 (2) Å; the dihedral angle between them is 74.1 (1)°. In both ligands, the thia­zole and benzimidazole rings are nearly coplanar, as indicated by the dihedral angles between their planes of 1.16 (8) and 6.29 (7)°. Each pendant benzene ring is almost perpendicular to the benzimidazole mol­ecule to which it is attached; the dihedral angles between their planes are 75.94 (9) and 75.55 (10)°. The crystal structure is stabilized by non-classical C—H...Cl hydrogen bonding forming a three-dimensional network.
