A New Mn(II) Coordination Polymer Based on Mixed 2-Aminoterephthalic Acid and 2,6-Bis(1-imdazoly)pyridine Ligands: Synthesis, Structure, and Luminescent Property

Abstract

A new Mn(II) coordination polymer, namely [Mn(impy)(NH2-pbc)]n (1 NH2-H2pbc = 2-aminoterephthalic acid, impy = 2,6-bis(1-imdazoly)pyridine), has been synthesized through solvothermal reactions of MnCl2, NH2-H2pbc and impy. Single X-ray structural analysis reveals that compound 1 features a 2D layered structure, and these 2D sheets are further stacked into a 3D supramolecular framework via weak van der Waals interactions. In addition, the luminescent properties of compound 1 and free impy ligand were also investigated at room temperature.
