| Abstract: The novel dinuclear copper(Ⅱ) complex with with N-(2，4-dihydroxybenzalidene)-o-aminobenzoic acid ligand， [Cu(C14H9NO4)]2·2H2O， has been synthesized and characterized by elemental analysis， IR， UV-Vis and thermal analysis. Its crystal structure was determined by single crystal X-ray diffraction techniques. The crystal belongs to monoclinic with space group P21/c. The cell parameters are: a=0.82510(11)nm， b=0.68870(9)nm， c=2.3007(3)nm， β=100.847(2)°， V=1.2840(3)nm3， Z=2，Dc=1.742Mg·m-3， μ(Mo Kα)=1.723mm-1， F(000)=684. The structure was refined to final R1=0.0267， wR2=0.0735. The complex molecule structure has dinuclear centrosymmetric dimeric structure in which a planar Cu2O2 core features. The ligand N-(2，4-dihydroxybenzalidene)-o-aminobenzoic acid dianion is μ2-tridentate， chelating one copper(Ⅱ) ion via one nitro-gen， one hydroxy oxygen atom and one carboxylate oxygen atom， and the hydroxy oxygen atom simultaneously co-ordinates to the other copper(Ⅱ) ion of the dimer. In the structure the copper(Ⅱ) ion rendered four-coordination in a distorted square-planar geometry structure. CCDC: 212695. |
