Abstract
The title binuclear complex, [Cd2Cl4(C14H10N4)2], was synthesized by the hydrothermal reaction of CdCl2 and the ligand 2,2′-bibenzimidazole. The molecule lies on an inversion center and the metal center displays a strongly distorted trigonal-bipyramidal geometry. The CdII ions are coordinated by two N atoms from the organic ligand, and by one terminal and two bridging chloride anions. The crystal structure involves intermolecular N—H⋯Cl hydrogen bonds, resulting in a one-dimensional supramolecular structure.
