通过水热法合成得到了一个包含四核镉(Ⅱ)的基于2-丙基-4,5-二甲酸咪唑和4,4-联吡啶的配位聚合物[Cd2(HPIDC)2(bpy)(H2O)2](1)。X-射线单晶衍射分析结果表明:配合物1属单斜晶系,结晶在c2/c空间群中,晶胞参数为:a=1.936 6(4)nm,b=1.504 1(3)nm,c=2.200 4(5)nm,β=94.990(4)°,V=6.385(2)nm3,Z=8,1.393 mm-1,F(000)=3 216,Dc=1.684 g.cm-3,R1=0.045 8,wR2=0.108 9。通过链间的O-H…O氢键作用,形成了三维的超分子结构。固体荧光测试表明:配合物1在427 nm处发射出较强的荧光。
A coordination polymer [Cd2 (HPIDC) 2 (bpy) based on 2-propyl-4,5-dicarboximidazole and 4,4-bipyridine containing tetranuclear cadmium (Ⅱ) (H2O) 2] (1). The results of X-ray single crystal diffraction analysis show that the complex 1 belongs to the monoclinic system and the crystallites are in c2 / c space group. The unit cell parameters are as follows: a = 1.936 6 (4) nm, b = 1.504 1 , d = 1.684 g · cm -1, c = 2.200 4 (5) nm, β = 94.990 (4) °, V = 6.385 nm 2, 3, R1 = 0.045 8, wR2 = 0.108 9. Through the O-H ... O hydrogen bonds between chains, a three-dimensional supramolecular structure is formed. Solid fluorescence test showed that complex 1 emitted strong fluorescence at 427 nm.
