Abstract

In the title compound, [CdBr(2)(C(30)H(26)N(4)S)]·C(3)H(7)NO, both the complex and solvent mol-ecule lie on a crystallographic mirror plane. The Cd(II) ion is coordinated in a disorted square-pyramidal CdBr(2)N(2)S environment with one of the Br atoms in the apical site. In the crystal structure, the benzimidazole ring systems are involved in weak inter-molecular π-π stacking inter-actions [centroid-centroid distances = 3.606 (2) and 3.753 (2) Å]. Further stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds. The methyl H atoms of the dimethyl-formamide solvent mol-ecule are disordered about a mirror plane.
