Abstract

A novel 2D {Co3} clusters coordination polymer, [Co3(Hdppd)2(H2O)6]n (1) based on 3-(2,4-dicarboxylatephenyl)-2,6-pyridinedicarboxylic acid ligand (H4dppd) has been synthesized and characterized by IR spectra and X-ray single crystal diffraction method. The results show that trinuclear clusters {Co3} are formed in complex 1 which are connected into 2D layer structure by bridging Hdppd3- ligands; neighboring 2D layers are further linked into 3D supramolecular polymers by intermolecular hydrogen bonds. In addition, thermal stability and magnetic property of complex 1 were also studied.
