Bis[2-(benzimidazol-2-ylsulfan­yl)acetato]bis­(2,2′-bipyridine)cadmium(II)

In the structure of the title compound, [Cd(C(9)H(7)N(2)O(2)S)(2)(C(10)H(8)N(2))(2)], the complex mol-ecules are located on a crystallographic twofold rotation axis and the Cd(II) ion is octa-hedrally coordinated by two chelating 2,2'-bipyridine ligands and two O atoms from the carboxyl-ate groups of two 2-(benzimidazol-2-ylsulfan-yl)acetate ligands. The two carboxyl-ate ligands adopt a cis configuration with respect to each other. Within each of these ligands, the imidazole fragments are bent back in a loop towards the acetyl groups, forming intra-molecular N-H⋯O hydrogen bonds, which help to stablilize the mononuclear complex. Adjacent mol-ecules are further linked by weak C-H⋯O hydrogen bonds, resulting in a chain along the c axis.
