A novel trinuclear cadmium(Ⅱ) supramolecular complex [Cd3(PDA)3(2,2'-bipy)3(H2O)2]· 2H2O (1) (H2PDA=pyridine-2,6-dicarboxylic acid) has been prepared under hydrothermal condition and characterized by elemental analysis, IR, TG, fluorescence spectrum and single-crystal X-ray diffraction. The complex crystallizes in monoclinic system, space group P21/n with a=2.122 81(14) nm, b=1.006 09(7) nm, c=2.830 64(19) nm, β=108.937 0(10)°. The structure of the complex consists of trinuclear units with all metal centers being seven-coordinated. Cdl, Cd2 and Cd3 atoms are bridged by three carboxylate groups in dimonodentate fashion to give a trinuclear molecular building block [Cd3N9(CO2R)6]. Intermolecular hydrogen-bond interactions and face-to-face π-π stacking interactions lead the complex to a 3D supramolecular architecture. Fluorescent analyses show that the complex exhibits intense blue photoluminescence at room temperature and may be potential candidate for photoactive material.
