Abstract
A novel complex Cu(dafo)(2)(NO3)(2). 2H(2)O was synthesized. The crystal st ructure data indicate that the Cu(II) ion was coordinated with the four nit rogen atoms through two ligands(dafo) respectively and two oxygen atoms thr ough two water molecules respectively. The two ligands(dafo)and Cu(II) ion were in the same plane, whereas the two water molecules were vertical to th e plane. The Cu(II) ion was in the center of the malformed octahedron. The crystal data is triclinic, P1 space group, a = 0.7987(2) nm, b = 1.0543 (1) nm, c = 0.70403(5) nm; alpha = 91.557(8)degrees, beta = 96.711(10)degrees, gamma = 94.45(1)degrees. UV and solid fluorescence spectra were analyzed. The vibration spectrum bf the complex was calculated with Hyper Chem 5.11 s oftware.
