题名: Synthesis, crystal structure and properties of a one-dimensional polymeric copper(II) complex of tetrachlorophthalate 作者: Yang, SY; Long, LS; 龙腊生; Wu, ZY; Zhan, MX; 詹梦熊; Huang, RB; 黄荣彬; Zheng, LS; 郑兰荪 摘要: The coordination polymer [Cu2L2(H2O)(6) . 2(H2O)](n) (L = mu-tetrachlorophthalate dianion) has been synthesized and characterized by X-ray crystallography, i.r. spectroscopy, electronic spectroscopy and cyclic voltammetry. The structure of the complex is a one-dimensional zigzag chain. The i.r. spectra reveal that the tetrachlorophthalate groups are bismonodentate ligands, and this is confirmed by the crystal structure determination. Cyclic voltammetry reveals two steps of a quasi-reversible oxidation-reduction processes for the complex.

题名: Study of the electrochemiluminescence based on tris(2,2 '-bipyridyl)ruthenium(II) and some nervous amine compounds using flow injection analysis 作者: Chen, X; 陈曦; Li, MJ; 李梅金; Li, Z; 李真; Yi, CQ; 易长青; Wang, XR; 王小如; Wang, B; 王波 摘要: A new electrochemiluminescence (ECL) method for the detection of methamphetamine (METH) and some nervous amine compounds is described. The pH of mobile phase and applied potential on glassy carbon electrode obviously influance the intensity of the ECL of METH. The mobile phase was selected as 0.1 mmpl/L Ru (bpy)(3)Cl-2 in 0.05 mol/L NaH2PO4-NaOH (pH 9.0) buffer. The studies of the effect of applied potential and flow rate on ECL showed that METH gives the brightest light emission at the potential of + 1.55 V and at the flow rate of 0.4 mL/min. A linear relationship was obtained from 6.84 x 10(-11) similar to 6.84 x 10(-3) mol/L with a correlation coefficient of R-2 = 0.9906 and the detection limit was 2 x 10(-1) mol/L under the experimental condition. We effect of surfactants on ECL was studied. The work also included the study of ECL of related compounds such as codeine, cocaine, morphine and so on. Cyclic voltammetry showed that their different oxidation currents might lead to their different ECL intensity. The method was simple, economical, sensitive, useful and provided some evidences for scout cases.

题名: Hydrothermal synthesis and crystal structure of the first ammonium indium(III) phosphate NH4In(OH)PO4 with spiral chains of InO4(OH)(2) 作者: Mao, SY; 毛少瑜; Li, MR; Huang, YX; Mi, JX; Chen, HH; Wei, ZB; Zhao, JT 摘要: An ammonium indium hydrogen phosphate, NH4In(OH)PO4, was synthesized under mild hydrothermal conditions, and the crystal structure was characterized by single-crystal X-ray diffraction method. The compound crystallizes with the RbIn(OH)PO4 type with the following data: M-r = 244.84, tetragonal, tP104, P4(3)2(1)2 (No.96), a = 9.416(2) Angstrom, c = 11.159(3) Angstrom, V = 989.9(3) Angstrom(3), Z = 8, D-x = 3.288g cm(-3) lambda = 0.71073 Angstrom, mu = 50.34 cm(-1), F(000) = 928, T = 293K, R1 = 0.0606, wR2 = 0.1472 for 91 variables and 1813 contributing unique reflections. The structure is characterized by chiral InO4(OH)(2) chains along the c axis formed by sharing OH corners. The chains are isolated by PO4 tetrahedra leading to a three-dimensional framework structure with channels occupied by NH4+ ions. The framework structure is similar to that of KIn(OH)PO4 and gamma-NaTiOPO4. The hydrogen bonds formed by NH4+ with the polyhedral oxygen atoms play an important role in the anisotropic changes of the lattice with respect to its alkali metal analogues. The topological construction of the title structure can be considered as an augmented 4,6-net with larger porosity. (C) 2002 Elsevier Science (USA).

题名: Bond valence parameters linearly dependent on the molybdenum oxidation states 作者: Chen, MD; Zhou, ZH; 周朝晖; Hu, SZ; 胡盛志 摘要: Based on the available crystal data, a linear correlation between R-0, the bond valence parameter for a Mo-containing chemical bond, and the Mo oxidation state n was developed for the first time. Using the "universal" value of the parameter B = 0.037 nm, the linear equations of R-0-n for Mo-X (X: 0, S, N, Cl and F) bonds were established. The oxidation-state independent Mo-O bond valence parameters, R-0 = 0.18788 nm and B = 0.03046 nm, published recently have been shown to be a special case of the linearly correlated functions. Some bond valence sum calculations in compounds containing only Mo-O bonds using these parameters are presented.
