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 (H 2 O) 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)(H 2 O) 2 ] are bridged by a 1,4‐bdc 2− to generate a coordination unit [Cd(8‐qoac)(bdc) 0.5 (H 2 O) 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.
