The crystal crystallizes in orthorhombic system, space group P bca with a =1 503 2(3), b =1 819 5(4), c =2 330 2(5) nm, V =6 373(2) nm, Z =8, D c = 1 348 g/cm 3 , μ =0 971 mm -1 (Mo Kα ), F (000)=2 720. The structure was refined to R =0 048 9 and wR = 0 094 3 for observed 2 978 reflections with I≥2σ(I) . The Zn(Ⅱ) ion has a distorted tetrahedral coordination consisting of two chlorine ions and the two oxygen atoms from two Schiff base ligands.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
