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=0.8750(2)nm,b=5.1226(12)nm,c=13.292(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。 A single crystal of two dimensional coordination polymer [Pb (ima) 2] n (1) was synthesized by sol-gel diffusion of lead acetate (Pb (Ac) 2 · 3H2O) and imidazole acetic acid (Hima) X-ray single crystal diffraction analysis showed that the crystal belongs to monoclinic space group P21 / n with unit cell parameters of a = 0.8750 (2) nm, b = 5.1226 (12) nm and c = 13.292 , β = 93.570 (4) °, V = 594.6 (2) nm3, Z = 2. The complex [Pb (ima) 2] n is a coordination polymer with two-dimensional topological structure of kgd. The two-dimensional layers are connected by C-H ... O hydrogen bonds to form three-dimensional supramolecular structure. The infrared, elemental, thermogravimetric and fluorescence properties of the complexes were studied.
