摘要
A new polymer [Zn2（cam）2（bpmp）]n 1 （H2cam = D-（＋）-camphoric acid, bpmp = bis（4-pyridylmethyl）piperazine） was synthesized under hydrothermal conditions. The compound crystallizes in the monoclinic system, space group P21/n with a = 12.305（9）, b = 12.945（9）, c = 13.619（10） A, β = 116.833（8）°, V= 1936（2）A3, Z = 4, Mr = 397.76, Dc= 1.365 Mg/m3,μ = 1.292 mm-1, F（000） = 832, the final R = 0.0578 and wR = 0.1678 for 2838 observed reflections with I 〉 2σ（I）. The compound presents a three-dimensional （3D） network extended by homochiral 2D layer and bpmp ligands. From the topology point of view, the structure could be described as a 3D 6-connected mab net with （44.610.8） topology. In addition, infrared spectroscopy, elemental analyses, thermogravimetric analysis and powder X-ray diffraction properties of 1 are also investigated.
