Poly[bis(μ-azido-κ2N1:N1)[μ-1,2-bis(imidazol-1-yl)ethane-κ2N3:N3′]cadmium]

In the title three-dimensional coordination polymer, [Cd(N3)2(C8H10N4)]n, the coordination geometry around the CdII atom is distorted octahedral. The CdII 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 CdII atoms form a one-dimensional zigzag chain constructed from four-membered [Cd(N3)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.
