Bis[1-benzyl-2-(1,3-thia-zol-4-yl)-1H-benzimidazole-?(2) N (2),N (3)]dichloridocobalt(II).

ABSTRACT: In the title compound, [CoCl2(C17H13N3S)2], the Co(II) atom exhibits a distorted octa-hedral 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-thia-zol-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 thia-zole 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 mol-ecule 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.
