摘要：
The title compound [Cd(Hq)2(Hdpa)2] (Hq = 8-hydroxyquinoline, H2dpa = diphe- nic acid) has been synthesized and characterized by single-crystal X-ray diffraction analysis. It crys- tallizes in monoclinic, space group C2/c with a = 20.6880(5), b = 14.2584(4), c = 13.4776(4) , ( = 113.434(2)(, C46H28Cd1N2O10, Mr = 881.10, V = 3647.68(17) 3, Z = 4, Dc = 1.604 g/cm3, F(000) = 1784, ( = 0.668 mm-1, the final R = 0.0576 and wR = 0.1157 for 2631 observed reflections with I > 2((I). The centrosymmetric Cd(II) ion is six-coordinated in a slightly distorted octahedral geometry. The intermolecular hydrogen bonds extend the mononuclear structure into a one-dimensional supramolecular framework. The fluorescence spectrum of the compound exhibits intense emission at 520 nm when excited at 330 nm in solid state at room temperature.
