The complexes were characterized by elemental analysis, XRD, UV, IR and 1H NMR. The crystal structure of the complexes belongs to triclinic system with the cell parameters: a =1 297 1 nm, b =1 621 0 nm, c =2 047 0 nm, α =85 40°, β =88 80°, γ =99 00° for [CuC 30 H 26 N 2O 4·0 5H 2O]; a =1 300 2 nm, b =1 882 6 nm, c =2 127 4 nm, α =86 47°, β =89 23°, γ =99 11° for [NiC 30 H 26 N 2O 4]; a =1 286 5 nm, b =1 596 1 nm, c =2 056 9 nm, α =87 95°, β =93 17°, γ =98 21° for [CoC 30 H 26 N 2O 4], respectively. The N and O atoms in the complexes appeared coordinated directly to the metal ions. A quadridentate chelate may be formed.展开更多
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 therma...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 (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
