A novel nickel(II) complex with 2,4-dihydroxybenzalidene benzoylhydrazone a nd pyridine ligands, Ni(C14H10N2O3)(C5H5N), has been synthesized and characteriz ed by elemental analysis and IR. The crystal structure of the title complex has been determined by single crystal X-ray diffraction techniques. The crystal belo ngs to orthorhombic, space group Pbca. The cell parameters are: a=1.580 20(19) n m, b=1.362 18(16) nm, c=1.616 50(19) nm, and V=3.479 5(7) nm3, Z=8, Dc=1.497 Mg ·m-3, composed of two oxygen atoms, one n itrogen atom of tridentate acyhydrazone schiff base ligand and one nitrogen atom of the pyridine ligand. The analysis of the crystal structure indicates that th e complex has a one-dimensional chain structure, which is formed by intermolecul ar hydrogen bonds. CCDC: 244668.
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.
