Catena-Poly[[(diiodidocadmium)-?-{1-[(1H-benzimidazol-2-yl)meth-yl]-1H-imidazole-?N:N'}] N,N-dimethyl-formamide monosolvate].


ABSTRACT: In the title complex, {[CdI(2)(C(11)H(10)N(4))]·C(3)H(7)NO}(n), the Cd(II) ion is four-coordinated by two N atoms from two 1-[(1H-benzimidazol-1-yl)meth-yl]-1H-imidazole (bmi) ligands and by two terminal I(-) anions in a distorted tetra-hedral geometry. One of the two I(-) anions is disordered over two sets of sites, with refined occupancies of 0.66?(5) and 0.34?(5). The Cd(II) ions are bridged by bmi ligands, leading to the formation of a chain along [001]. Dimethyl-formamide solvent mol-ecules are located between these chains. Classical N-H?O hydrogen bonding between the bmi ligands and the solvent mol-ecules leads to a consolidation of the structure.
