Catena-Poly[[tetraaquacadmium]-μ-5,5′-(1,4-phenylene) di(tetrazol-2-ido)-κ2 N 2:N 2′]

Abstract

In the title compound, [Cd(C8H4N8)(H 2O)4]n, 5,5′-(1,4-phenylene)di(tetrazol- 2-ide) (L) ligands bridge CdII atoms into polymeric chains along [201]. The CdII atom is situated on an inversion centre and is coordinated by two N atoms from two L ligands and by four water O atoms in a distorted octahedral geometry. In the L ligand, the benzene ring resides on an inversion centre and the tetrazole rings are twisted from its plane by 22.3 (1)°. An extensive hydrogen-bonding network formed by classical O - H⋯N and O - H⋯O interactions consolidates the crystal packing, linking the poymeric chains into a three-dimensional structure.
