Abstract

A new three-dimensional(3D) coordination polymer, [Cu(atz)(isonic)]n (1) was synthesized hydrothermally from mixed-ligands of Hatz (Hatz=5-amino-1H-tetrazole) and Hisonic (Hisonic=isonicotinic acid) and corresponding CuII salt. It was characterized by IR spectra, elemental and thermal analysis, structurally and magnetically characterized. In this compound, CuII ions are linked by μ3-atz bridges to give [{Cu2(μ3-atz)2}]2+ cationic layer. The cationic layers are further pillared by isonic ligand and resulted in 3D frameworks with unprecedented topological network. The variable temperature magnetic investigations indicate that compound 1 exhibits typical antiferromagnetic behaviors.
