Abstract
Abstract A new coordination polymer [Cd(C10H8N2)2 (C10H4O8)] n (C10H8N2 = 2,2′-bipyridine and C10H4O8 = 2,5-dicarboxybenzene-1,4-dicarboxylate) has been hydrothermally synthesized and characterized by elemental analysis, infrared spectroscopy, thermal gravimetric analysis and single-crystal X-ray diffraction. Crystal structural analysis reveals that the CdII cation is coordinated by two 2,5-dicarboxybenzene-1,4-dicarboxylate ligands and two 2,2′-bipyridine molecules, forming a distorted octahedral CdN4O2 coordination geometry. The 2,5-dicarboxybenzene-1,4-dicarboxylate ligands link the CdII cations to generate a one-dimensional metal-organic structure running along the [0 1 0] direction. Adjacent chains are further connected by carboxyl-carboxyl O–H···O hydrogen bonds, resulting in a two-dimensional supermolecular architecture running parallel to the (1 0 0) plane in the solid state. The fluorescence properties of the complex were investigated.
