摘　　要：The complex Cu(phon)(NO3)2(CH3CN) (phon = 1,10-phenanthroline-5,6-dione) has been synthesized and characterized by elemental analysis, infrared and UV-Vis spectra. 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.
