| 摘要: 醋酸铅(Pb(Ac)2·3H2O)和咪唑乙酸(Hima)通过溶胶凝胶扩散合成二维配位聚合物[Pb(ima)2]n (1)的单晶。X-射线单晶衍射分析表明，晶体属于单斜晶系，P21/n空间群，晶胞参数为：a=0.875 0(2) nm，b=5.122 6(12) nm，c=13.29 2(3) nm，β=93.570(4)°，V=594.6(2) nm3，Z=2。配合物[Pb(ima)2]n是一个具有二维kgd拓扑结构的配位聚合物，二维层间又通过C-H…O氢键连接形成三维超分子结构。对配合物的红外、元素、热重及荧光等性质进行了研究。 |

| Abstract: The reaction between Pb(Ac)2·3H2O and 2-(1H-imidazole-1-yl) acetate (Hima) produced a neutral 2D coordination polymer [Pb(ima)2]n (1). The single crystals were obtained by diffusing through agar gel aqueous solution and structurally characterized by single-crystal X-ray diffraction analysis. The polymer crystallized in the monoclinic space group P21/n with the cell parameters: a=0.875 0(2) nm, b=5.122 6(12) nm, c=13.292(3) nm, β=93.570(4)°, V=594.6(2) nm3, Z=2. The [Pb(ima)2]n represents a (3,6)-connected 2D layer with kgd topology, which further stacks into 3D supramolecular networks through C-H…O weak interactions. The polymer is also characterized by IR, elemental analysis, fluorescent properties and thermogravimetric analysis. CCDC: 773324. |
