Coordination polymers formed by bridging 2-substituted tetrazole ligands: poly[[dichlorocopper(II)]-di-[bold mu]2-2-propyl-2H-tetrazole-[bold kappa]2N1:N4] and poly[[dichlorocopper(II)]-di-[bold mu]2-2-allyl-2H-tetrazole-[bold kappa]2N1:N4]

Abstract: Two polymeric complexes, [CuCl2L2]n, where L is 2-propyltetrazole (C4H8N4) or 2-allyltetrazole (C4H6N4), are the first coordination polymers of 2-substituted tetrazoles in which only the tetrazole rings bridge neighbouring Cu atoms. In both complexes, the Cu atoms lie on inversion centres and are six-coordinated in tetragonally distorted octahedral geometries, CuCl2N4, with two N1 tetrazole ring atoms in the axial positions and two Cl atoms and two N4 tetrazole ring atoms in the equatorial sites. The Cl atoms do not participate in the polymeric layer formation.

Formula: [CuCl2(C4H8N4)2] and [CuCl2(C4H6N4)2]
