Poly[bis(mu-azido-kappa N-2(1):N-1)[mu-1,2-bis-(imidazol-1-yl)ethane-kappa N-2(3):N-3']- cadmium]

In the title three-dimensional coordination polymer, [Cd(N 3) 2(C 8H 10N 4)] n, the coordination geometry around the Cd II atom is distorted octahedral. The Cd II atom is coordinated by two N atoms from two cis-positioned bridging 1,2-bis-(imidazol-1-yl)ethane (bime) ligands and four N atoms from four azide anions. Each azide ligand acts in an end-on bridging coordination mode. The azide ligands and Cd II atoms form a one-dimensional zigzag chain constructed from four-membered [Cd(N 3) 2] n metallacycles extending along the a axis. These inorganic chains are connected with four other chains via bridging bime ligands to form a three-dimensional coordination network.
