Abstract
A hetrobimentallic complex of Zn[Bi(edta)]2•8H2O was synthesized under hydrothermal condition and characterized by means of X-ray single crystal diffraction, element analysis, FT-IR spectra and thermal analysis. The complex is monoclinic, space group C2/c with a =2.3532(8) nm, b=0.8675(3) nm, c=1.6116(6) nm, β=98.114(6) °, V=3.2569(19) nm3, Z=4，Dc= 2.455 g•cm－3，μ= 11.615mm－1. Bridging edta4－ anions between Bi(III) atoms result into infinite 1D zigzag chain. [Bi(edta)]－anions and [Zn(H2O)6]2+ cations are bonded through hydrogen bonds to form network structure. The thermal decomposition of the complex proceeds dehydration, pyrolysis of ligand, and decomposition of salt, and the final residue is inorganic oxide. The thermodynamic parameters ( ΔH、ΔG and ΔS) and kinetic parameters (activation energy Ea and the pre-exponential factor A) for the pyrolysis of ligand have been calculated.
