Employing an unsymmetrical 1,2,4-benzenetricarboxylate as a bridging ligand, a new 3-D chiral cadmium coordination polymer [Cd(2)(OH)(1,2,4-BTC)] (1,2,4-BTC = 1,2,4-benzenetricarboxylate) has been prepared under hydrothermal conditions and characterized by single crystal X-ray diffraction. This compound crystallizes in the orthorhombic space group P2(1)2(1)2(1), with cell parameters a = 6.900(2) A, b = 7.404(3) A, c = 19.116(5) A, V = 976.5(5) A(3), and Z = 4. Its structure contains 2-D Cd-O-Cd connectivity, which is further linked by the 1,2,4-BTC ligand into a 3-D supramolecular framework. The 1,2,4-BTC ligand shows a novel and unprecedented coordination mode: nine bonds to eight metals with each carboxylate as a tridentate group. The compound exhibits intense photoluminescence at room temperature and shows distinct NLO properties. On the basis of the results of TG/DTA analyses, the structure is thermally stable up to approximately 380 degrees C.

A bismuth-based organic-inorganic hybrid material with layered structure (BiO-BTCIE) was synthesized by taking advantage of an ion exchange reaction. The structure of BiO-BTCIE was examined by XRD, EXAFS, FT-IR, TG/DTA, etc. By replacing the HCOO(-) with BTC anions in the Bi2O2(2+) interlayer, the Bi2O2(2+) layer is distorted as revealed by the EXAFS, which lead to a longer life time of the photogenerated charge carriers and a higher photocatalytic activity of BiO-BTCIE (more than 10 times).
