X-ray diffraction analysis at room temperature indicates that the complex crystallizes in orthorhombic system, space group P212121 with a = 8.353(1), b = 11.299(2), c = 17.764(2) A, V= 1676.5(4) A3, Z = 4, C14H9CuN5O8, Mr = 438.8, Dc = 1.739 g/cm3, F(000) = 884 and μ(MoKα) = 1.361 mm-1. The final R and wR factors for the observed reflections with I > 2σ(I) are 0.0353 and 0.0855, respectively. R = 0.0432 and wR = 0.0899 for all data. The structure of the title complex consists of a neutral mononuclear entity. The central Cu (II) atom is five-coordinated by two nitrogen donors of one ligand, two unidentate NO3- ions and one CH3CN molecule. The coordination geometry of Cu (II) can be considered as a distorted trigonal bipyramidal configuration. The complex ability of the NO3-ion has more effect than that of the ClO4- ion on the structure of the complex.展开更多

X-ray diffraction analysis at room temperature indicates that the complex （C40H28Cl2CuN8O16, Mr = 1011.14） crystallizes in orthorhombic system, space group P212121 with a=13.983（1）, b=14.310（1）, c= 20\^890（2） , V = 4179.7（6） 3, Z = 4, Dc = 1.607 g/cm3, F（000） = 2026,μ（MoKα） = 0.736 mm-1. The final R and wR factors are 0.0446 and 0.1212 respectively with 8545 independent reflections. The title complex is composed of a discrete [CuL3]2+ cation, uncoordinated ClO4- anions, H2O and CH3CN molecules. The central Cu（II） atom is six-coordinated by six nitrogen donors of three ligands. The coordination geometry of Cu（II） could be considered as an approximately ideal octahedral configuration with little static Jahn-Teller distortion （the longest and shortest Cu-N bonds are 2.102 vs 2.139 with the mean length of 2.122 ）, which is very rare for a six-coordinated Cu（II） complex.展开更多

The two novel compounds were confirmed by means of elemental analysis, IR, LDMS and 1H NMR , and 1H NMR spectra were completely assigned in virtue of 1H 1H COSY. The electrochemical behavior of the binuclear Ru(Ⅱ) complex was obtained using cyclic and squarewave voltammetry. Its photophysical property was investigated by electronic absorption, fluorescence excitation and emission spectra.展开更多
