【 摘 要 】

Two novel binuclear metal-organic coordination complexes [Cd2(L)2(bpy)2(H2O)2]·6H2O (1), [Cd2(L)2(phen)2- (H2O)2]·2H2O (2) (where L = 2-methylquinoline-3,4-dicarboxylate dianion, bpy = 2,2`-bipyridine, phen = 1,10- phenanthroline) have been synthesized under hydrothermal conditions and characterized by single crystal Xray diffraction, spectral method (IR), elemental analysis and thermal gravimetric analysis (TGA). Both 1 and 2 consist of two Cd(II) atoms bridged by two monoatomic bridging carboxylate groups from two L ligands, and the second carboxylate group of each L is monodentately coordinated to Cd(II), creating a sevenmembered chelating ring. The coordination at each metal nucleus is completed by a water molecule and a chelating bidentate molecule. The 3D structures of the complexes are stabilized by π-π stacking interactions and hydrogen-bonds.
