摘　　要：The title complex [CuL3]（ClO4）2·2H2O·2CH3CN （L = 1,10-phenanthroline-5,6-dione） has been synthesized and characterized by elemental analysis, conductivity, infrared and UV-Vis spectra. 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.
