摘要：
The novel complex [Zn_2(Mba)_3(Phen)_2EtOH)]·ClO_4 (Hmba=methoxybenzoic acid, Phen=1,10-phenanthroline, EtOH=ethanol) was synthesized by hydrothermal reactions, and its structure was determined by X-ray diffraction. The crystal belongs to the triclinic system, space group Pi with a=1.15362(1), b=1.3655(3), c=1.61451(1) nm, α=72.842(2), β=83.259(3), γ=72.083(2)°, V=2.3112(6) nm3, Z=2, μ(MoKα)=11.71 cm~(-1), F(000)=1120, R=0.0552 and wR=0.1157 (I > 2σ(I)). The two centric zinc(Ⅱ) ions in the complex locate in a distorted octahedral coordination geometry and a distorted trigonal bipyramid coordination geometry, respectively. Two bridging bidentate carboxyl groups and a μ_2-O carboxyl group from three methoxybenzoic acids act as the bridge to link two Zn(Ⅱ) ions. The asymmetric units are connected by π-π packing interactions between aromatic rings to form a three-dimensional supramolecular network. The experimental results show a good fluorescence property for the complex.

摘要：
A complex [Cu(2,2'-bipy)( BAA)][Cu(2,2'-bipy)( BAA)(H2O)](2)center dot(H2O)(3) (BAA=benzilic acid anion, 2,2'-bipy=2,2'-bipyridine) has been synthesized. Crystal data for this complex are as follows: triclinic, space group P1, a=1.121 7(5) nm, b=1.360 2(6) nm, c=2.335 2(10) nm, alpha=99.260(6)degrees, beta=101.223(8)degrees, gamma=94.805(8)degrees, V=3.425(3) nm(3), D-c=1.385 g.cm(-3), Z=6, mu(Mo K alpha)=0.992 mm(-1), F(000)=1 474, final discrepancy factors R-1=0.056 1, wR(2)=0.112 8. There are three mononuclear copper(II) complexes in one asymmetric unit of the compound, where the three central Cu(II) ions are not all of the same coordination number. Cu(1) ion is tetra-coordinated, while Cu(2) ion and Cu(3) ion are both penta-coordinated. The cyclic voltammetric behavior and fluorescent property of the title compound were investigated. The results show that the electron transfer in the electrode reaction of the title complex is irreversible, and two electrons are involved in the oxidation of the title complex. When the exciting radiation setting at 478 nm, the title complex can give off fluorescent emission. CCDC: 788067.
