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

•A new Mn coordination polymer with mixed-ligands has been synthesized.•The 3D framework was proved by single-crystal X-ray diffraction.•Title compound shows an unprecedented topological net.

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.

Graphical abstractA new coordination polymer, Mn2(atz)(isonic)(OH)(Cl)]n has been firstly synthesized by employing mixed-ligand synthetic approach. Compound 1 presents a 3D framework with an unprecedented (3,6,6)-connected topological network.Figure optionsDownload full-size imageDownload as PowerPoint slide
