| Abstract: | A 3-D cadmium(II) organic framework with a fourfold interpenetrated diamond topological structure, {CdLBDC]·(H2O)2}n (1), was synthesized through zwitterionic ligand H3LBr3 (1,1′,1″-(2,4,6-trimethylbenzene-1,3,5-triyl)-tris(methylene)tris(4-carboxypyridinium)tribromide), secondary ligand H2BDC (1,4-benzenedicarboxylic acid) and Cd(NO3)2·4H2O by solvothermal method. Compound 1 was characterized by elemental analyses, FT-IR spectroscopy, powder, and single-crystal X-ray diffraction and thermogravimetric analysis. The photophysical properties of 1 were investigated by solid-state diffuse reflectance spectrum. In 1, each L is linked by two separate Cd(II)-centered distorted tetrahedra, which are also linked by two L, thereby forming a head-to-tail connected 2-D layer structure and further building the 3-D framework through BDC2?-chelating-bridging between layers. |
