A Zigzag Chain Cd (II) Coordination Polymer Based on 2,4-Dinitro-benzoic Acid Ligand: Syntheses, Structure and Photoluminescence

摘要

The coordination polymer, namely, [Cd(L)_2(phen)]_n (1) (HL=2,4-dinitro-benzoic acid, phen=l,10-phenanthroline) has been hydrothermally synthesized. Compound 1 was structurally characterized by IR spectra, thermogravimetric analysis and single-crystal X-ray diffractions. The carboxylate groups of L~- adopt the bridging monodentate and bidentate modes to link two Cd~(2+) ions, resulting in a 1-D zigzag chain structure. The solid state photoluminescent property of 1 has been investigated at room temperature.
