Hydrothermal Synthesis, Crystal Structure and Thermal Property of a Coordination Polymer Constructed by Ce(Ⅲ) and Succinate Ions

论文摘要

A new three-dimensional coordination polymer [Ce2（C4H4O4）3（H2O）2]n·3.2 nH2 O, constructed by Ce（Ⅲ） ion and succinate ion and lattice water molecules has been synthesized under hydrothermal conditions. It crystallizes in triclinic system, space group P1 with a = 7.8865（6）, b = 12.0260（8）, c = 12.2598（9） ?, α = 112.456（2）o, β = 90.046（2）o, γ = 100.423（2）o, Mr = 722.14, V = 1053.73（13） ?3, Z = 2, Dc = 2.276 g/cm3, μ = 4.35/mm, F（000） = 696, GOF = 1.029, R = 0.0203 and w R = 0.0570. The asymmetric unit contains two Ce3+ cations and both of them are nine-coordinated and their coordination geometries can be described as two distorted monocapped square antiprisms. In the title compound, a three-dimensional coordination network with one-dimensional hexagon honeycomb-like channels along the a axis is generated. TG measurement has been carried out, and its result analysis along with the powder XRD determination indicates the residue to be CeO2.
