摘要

A new monomolecular copper(II) complex, [Cu(Phen)(2)(Pda)] center dot 9H(2)O (I) (H(2)Pda = pyridine-2,4-dicarboxylate acid, Phen = 1,10-phenanthroline), has been prepared from H(2)Pda and Phen at room temperature and characterized by IR, elemental analysis, X-ray powder diffraction, and single-crystal X-ray diffraction. Structure analysis shows that each Cu(II) is coordinated by two Phen ligands and one Pda ligand to complete a octahedron CuN(5)O chromophore. In addition, a unique water networks paralleling to (001) composed by the crystallization water through hydrogen bonds play a important role in the stability of crystal structure. The crystal structure is found to be orthorombic with space group Pbcn and cell parameters a = 13.651(4), b = 22.516(7), c = 22.386(7) , R (1) = 0.0735 and wR (2) = 0. 0.1935.
