Synthesis, structure and magnetic properties of manganese(II) coordination polymer with azido and zwitterionic dicarboxylate ligand

A coordination polymer formulated as {[Mn2L(N3)4]·2H2O}n(1) [L = 1,4-bis(pyridinil-3-carboxylato)-l,4-dimethylbenzene] was synthesized and structurally and magnetically characterized. The uniform Mn(II) chains with mixed (μ-EO-N3)2(μ-COO) triple bridges (EO = end-on) are linked by L ligands to generate a 2-fold interpenetrating 3D framework. Meanwhile, magnetism analysis reveals antiferromagnetic coupling for 1.

The uniform Mn(II) chains with mixed (μ-EO-N3)2(μ-COO) triple bridges (EO = end-on) are linked by L ligands to generate a 2-fold interpenetrating 3D framework and magnetism analysis reveals dominant antiferromagnetic coupling for 1.Figure optionsDownload as PowerPoint slide
