Synthesis, crystal structure and magnetic properties of manganese(II) coordination polymer from isonicotinate and amino-tetrazole mixed-ligands

A new 3D coordination polymer, Mn2(atz)(isonic)(OH)(Cl)]n (1), was synthesized hydrothermally from mixed-ligands of Hatz (Hatz = 5-amino-tetrazolate) and Hisonic (Hisonic = isonicotinate) and corresponding metal salts. It was characterized by IR spectra, elemental and thermal analysis, single crystal and powder X-ray diffraction. Variable temperature magnetic investigations indicate that compound 1 exhibits typical antiferromagnetic behaviors.
