文摘A new 3D heterometallic coordination polymer, namely [K2Pr2（C2O4）4·H2O]n（1）, has been successfully synthesized under hydrothermal conditions. X-ray single-crystal diffraction determination reveals that 1 crystallizes in monoclinic system, space group P21/n with a = 12.060（4）, b = 8.493（3）, c = 15.776（5）（A）, β = 93.235（3）°, V = 1613.4（9） A3, Z = 4, Mr = 730.12, Dc = 3.006 Mg/m^3, μ = 6.581 mm-1, F（000） = 1368, the final R = 0.0283 and wR = 0.0866 for 2939 observed reflections with I 〉 2σ（I）. Complex 1 features an unusual 3D heterometallic coordination framework, in which oxalates exhibit three different coordination behaviours. Moreover, powder X-ray diffraction and thermal properties for 1 have also been investigated.
