摘要
Quinoline-8-oxy-acetate acid （8-qoacH） reacts with M（Ⅱ） （M=Pb and Cd） to give rise to two coordination complexes [Pb（8-qoac）2] （1） and [Cd（8-qoac）（bdc）0.5（H2O）2] （2） under hydrothermal conditions. They are charac- terized by single-crystal X-ray diffraction, IR, elemental, thermal analyses and luminescent analysis. The Pb metal centers connect the 8-qoac anions to form a 1D linear chain in 1. In 2, two symmetrical [Cd（8-qoac）（H20）2] are bridged by a 1,4-bdc2 to generate a coordination unit [Cd（8-qoac）（bdc）0.s（H20）2], and all the units are further con- nected to a 2D supramolecular layer-like structure via hydrogen bonds. TG analyses indicate that 1 exhibits higher thermostability than 2. Fluorescence spectrum of compound 2 in solid state shows strong fluorescence property.
