A novel three-dimensional cadmium(II) coordination polymer constructed from dinuclear molecular building block, syntheses, structure and photoluminescence property

A novel cadmium(II) coordination polymer, [Cd2(pzdc)2(4,4′-bpy)2]·4H2O (1) (H2pzdc = pyrazine-2,3-dicarboxylic acid; 4,4′-bpy = 4,4′-bipyridine), has been synthesized by hydrothermal reaction of Cd(OAC)2, H2pzdc and 4,4′-bpy. Single-crystal X-ray diffraction analysis reveals that 1 constructed from dinuclear building blocks has a three-dimensional (3-D) structure with rob topology. Fluorescent measurement of 1 exhibits strong blue-green emission in the solid state at room temperature, and its framework possess remarkable thermal stability.
