| 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. CCDC: 860811. |
