A New Two-dimensional Cd(Ⅱ) Complex Assembled by 1,3,5-Benzenetricarboxylic Acid and 3-(2-Pyridyl)pyrazole

论文摘要

A new 2D coordination polymer, {[Cd5(BTC)2(L)4(H2O)2]n·2H2O}n(1, H3BTC = 1,3,5-benzenetricarboxylic acid, HL = 3-(2-pyridyl)pyrazole) was synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, powder XRD, IR, TGA, fluorescence spectrum and elemental analysis techniques. Complex 1 belongs to the monoclinic system, P21/c space group, with a = 8.8732(4), b = 17.5179(7), c = 17.8123(7) ?, β = 103.1830(10)°, V = 2695.77(19) ?3 and Z = 2. It features a 2D network constructed by BTC and L ligand. In addition, we analyzed Natural Bond Orbital(NBO) by using the PBE0/LANL2DZ method built in Gaussian 09 Program. The calculation results indicated obvious covalent interactions between the coordinated atoms and Cd(Ⅱ) ion.
