A 3D coordination polymer with 1D channels of [{NaCd4(IDC)3(prz)}·3H2O]n(1) (H3IDC=imidazole-4,5-dicarboxylic acid, prz=piperazine) was hydrothermally synthesized, and characterized by single-crystal X-ray diffraction. The crystal belongs to monoclinic system, space group Cc. There are four crystallographically independent Cd(Ⅱ) ions in the crystal lattice. Three Cd(Ⅱ) atoms form a small ring, and six Cd(Ⅱ) atoms form a large ring. The rings are further connected by the coordination interactions of IDC3- and Cd(Ⅱ) to generate a novel 3D frameworks containing 1D hexagonal channels, which is occupied by water molecules and Na+ ions. The compound displays strong blue fluorescent emission at room temperature. CCDC: 688709.
