【Abstract】 An one-dimensional(1D) zigzag ribbon of [Cd2(HPIDC)2(bpy)(H2O)2](1),containing rare square tetranuclear cadmium(Ⅱ) structural units,has been hydrothermally synthesized by using Cd(NO3)2·4H2O,2-propyl-imidazole-4,5-dicarboxylate(H3PIDC) and 4,4-bipyridine(bpy) as building blocks.The analysis of the single crystal X-ray diffraction result indicates that 1 crystallizes in monoclinic system,space group C2/c with a=1.936 6(4) nm,b=1.504 1(3) nm,c=2.200 4(5) nm,β=94.990(4)°,V=6.385(2) nm3,Z=8,μ=1.393 mm-1,F(000)=3 216,Dc= 1.684 g·cm-3,R1=0.045 8,wR2=0.108 9.The 1D zigzag ribbon extends to a 3D supramolecular network through inter-chain O-H…O hydrogen interactions.Photoluminescent measurement indicates that 1 shows maximum emission at 427 nm in the solid state at room temperature.更多还原
