Dibromido[1,1'-dibutyl-2,2'-(pentane-1,1-di-yl)di-1H-benzimidazole]-copper(II).

ABSTRACT: In the title compound, [CuBr(2)(C(27)H(36)N(4))], the Cu(II) ion exhibits a distorted tetra-hedral coordination geometry provided by two bromide ions and by chelation of two imine N-atom donors from a bis-(benzimidazole) ligand. Chelation results in a six-membered boat-shaped ring which links the benzimidazole groups. Each bis-(benzimidazole) fragment contains three n-butyl substituents, two of which have the expected trans conformation; the third exhibits the higher-energy cis conformation, an orientation consistent with several short intra-molecular C-H⋯Br inter-actions. Essentially planar (r.m.s. deviations of 0.0101 and 0.0183 Å) benzimidazole groups are oriented so as to give the bis-(benzimidazole) fragment a V-shaped appearance in profile with the cis and trans n-butyl groups direct
