| 英文摘要 | Two eight-coordination containing square antiprism polyhedra, [Ln(Gly)(4)Im-(ClO4)(4)](n), (Ln:Nd, Sm) were synthesized through the self-assembly of Ln3+ (Ln:Nd, Sm) ions, glycine and imidazole in aqueous solution and characterized by X-ray single crystal diffraction. Both of the complexes crystallized in the C2/c space group. In the cluster, each Ln(3+) ions was eight-coordination by eight oxygen atoms of the glycine. The coordination sphere of each Ln(3+) ions could be described as a distorted square antiprism. Two central Ln(3+) ions were connected by four bridging carboxyl groups from four glycine molecules. The Ln -O bond distances were related to the coordination geometries of the ligands. The complexes had two special solid solid phase transitions at 224 K and 248 K, which were interpreted as a freezing-in phenomenon of the reorientational motion of perchlorate ions Clai and the orientational order/disorder process of Cla.i ions. The decomposition mechanism of the complexes was deduced to be three stages from 300 to 700 K The fluorescent excitation and emission spectra showed that the complexes had strong fluorescent property.
