Coordination polymers formed by bridging 2-substituted tetrazole ligands: poly[[dichlorocopper(II)]-di-μ2-2-propyl-2H-tetrazole-κ2N1:N4] and poly[[dichlorocopper(II)]-di-μ2-2-allyl-2H-tetrazole-κ2N1:N4]
摘要:
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 N-1 tetrazole ring atoms in the axial positions and two Cl atoms and two N-4 tetrazole ring atoms in the equatorial sites. The Cl atoms do not participate in the polymeric layer formation.
