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 (MoKα )=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 μ 2 tridentate, chelating one copper? ion via one nitrogen, one hydroxy oxygen atom and one carboxylate oxygen atom, and the hydroxy oxygen atom simultaneously coordinates to the other copper? ion of the dimer. In the structure the copper? ion rendered four coordination in a distorted square planar geometry structure. CCDC: 212695.展开更多
