A chloro-bridged dinuclear copper(II) complex with ligand 2-pyridylme-thylene-furfurylamine has been synthesized and characterized by single-crystal X-ray diffraction, and its inhibitory activity on xanthine oxidase (XO) was also evaluated. It crystallizes in the triclinic system, space group P1 with a=8.0441(16), b=8.5663(17), c=10.060(2), α=77.52(3), β= 72.04(3), γ=70.12(3)°, V=615.3(2)3, Z=1, Dc=1.731 g/cm3, F(000)=322, the final R= 0.0401 and wR=0.0934 for 1971 observed reflections with I > 2σ(I). X-ray analysis reveals that the Cu(II) cation is five-coordinated by two N atoms of Schiff base and three Cl anions. The C-H…Cl intermolecular and intramolecular hydrogen bonds connect the molecules to form a three-dimensional network. This copper(II) complex shows more potent inhibitory activity against XO with IC50=3.48 μM than the standard inhibitor allopurinol. 相似文献

The Cu atom in the complex is five-coordinated in a square pyramidal geometry by three donor atoms of the Schiff-base ligand, and two N atoms from two bridging azide ligands. The [2,4-dibromo-6-[(3-dimethylaminopropylimino)methyl]phenolato]copper(II) units are linked by the bridging azide ligands, giving zigzag polymeric chains with backbones of the [--Cu-N-N-N--Cu]n type running along the b axis. 相似文献

The hydrothermal reaction of copper chloride dihydrate and 5,5-dimethyl-imidazolidine,-2,4-dione with a mole ratio of 1:1 in acetonitrile resulted in the formation of a new acetate-bridged dinuclear copper complex, [C2H6ON]2[Cu2Cl2(μ-CH3COO)4]. Protonated acetamide in eaolie form and acetic acid were yielded by the hydrolysis of acetonitrile under hydrothennal condition. The rifle complex (C12H24Cl2Cu2N2O10) was characterized by X-ray single-crystal diffraction, IR spectrum, elemental and electrochemical analysis. It crystallizes in the monoclinic system, space group P21/c with a = 8.298004), b = 14.358(2), c = 12.0010(2) A^°, β= 130.620(3)°, V = 1085.3(2) A^°^3, Dc = 1.696 g/cm^3, 34, = 554.31, Z = 2, F(000) = 564 and μ = 2.254 mm^-1. The crystal structure consists of a tetraacetate-bridging dinulcear copper complex anion [Cu2Cl2(μ-CH3COO)4]^2-, with the chlorine anions in the axial positions, and two protonated acetamide cations [C2H6ON]^+, which were connected through hydrogen bonds to form a three-dimensional infinite network. 相似文献

A novel copper(Ⅱ) complex with tert-butyl 2-[N-(tert-butyloxycarbonylmethyl)-2-picolyamino]acetate(ampy) was synthesized and structurally characterized by elemental analysis, FT-IR spectrum, electrospray ionization-mass spectrometry, UV-vis spectrum and single-crystal X-ray diffraction, respectively. A mononuclear copper(II) complex with ampy, [Cu(ampy)Cl2](1), was formed irrespective of the metal-to-ligand molar ratios([Cu2+]:[ampy] = 0.5:1, 1:1, and 2:1) as a single product. Complex 1 crystallizes in the orthorhombic system, space group Pbca with a = 12.343(2), b = 18.928(3), c = 20.058(4) ?, V = 4686.1(14) ?3, Z = 8, Dc = 1.3349(4) g/cm~3, F(000) = 1920, S = 1.016, R = 0.0693 and w R = 0.1721 for 3151 observed reflections with I 2σ(I). X-ray diffraction analysis reveals that the central copper(II) ion is bound by pyridyl N, tertiary amine N and carbonyl O atoms of the quadridentate ampy as well as two Cl anions, constructing a slightly distorted octahedral geometry. Complex 1 further constructs a stable 3D supramolecular architecture by intermolecular C–H···Cl hydrogen bonds. In addition, the molecular geometry was calculated by density functional theory(DFT/B3LYP) method with the basis sets(6-31+G(d,p) for H, C, N, O and Cl atoms, and LANL2 DZ for Cu atom, respectively). The calculated results show that the optimized geometrical parameters are in good agreement with the experimental data. Natural bond orbital(NBO) analysis and frontier molecular orbitals(FMOs) analysis were investigated at the same level. 相似文献
