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 characterized 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)(H2O)2] are bridged by a 1,4‐bdc2− to generate a coordination unit [Cd(8‐qoac)(bdc)0.5(H2O)2], and all the units are further connected 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.
