合成了标题配位聚合物,借助于元素分析、红外光谱和X射线单晶衍射等分析方法确定了其晶体结构,并测定了其TDA DTA。该配位聚合物属正交晶系,Pbcn空间群,晶胞参数为a=2.2012nm(6),b=0.7778nm(2),c=1.9724nm(5),α=β=γ=90°,V=337.70nm(15)3,Z=4,Dc=1.796g·cm-3,μ=3.108mm-1,F(000)=1800,R1=0.0430,wR2=0.0560。波谱分析结构显示,通过己二酸配体羧基氧原子桥联Nd3+离子形成三维多孔结构,4,4’bpy通过氢键连接存在于孔道中。
The title coordination polymer was synthesized. The crystal structure of the title coordination polymer was determined by means of elemental analysis, infrared spectroscopy and single crystal X-ray diffraction analysis. The TDA DTA was also determined. The coordination polymer belongs to orthorhombic and Pbcn space group. The unit cell parameters are a = 2.2012nm (6), b = 0.7778nm (2), c = 1.9724nm °, V = 337.70nm (15) 3, Z = 4, Dc = 1.796g · cm-3, μ = 3.108mm-1, F (000) = 1800, R1 = 0.0430, wR2 = 0.0560. Spectral analysis of the structure showed that the Nd3 + ions were bridged by the ligand of the adipic acid ligand to form a three-dimensional porous structure, and 4,4’-bipy existed in the pore by hydrogen bonding.
