以NdCl3·xH2O,ad(己二酸)和4,4’_bpy为原料,在水热合成反应条件下,合成了配位聚合物[Nd2(ad)3(H2O)2]n·n(4,4’_bpy),利用元素分析、红外光谱、X射线单晶衍射和荧光分析对其进行了表征.该配位聚合物属正交晶系,Pbcn空间群,晶胞参数为a=2.2012(6)nm,b=0.7778(2)nm,c=1.9724(5)nm,α=β=γ=90°,V=3.3770(15)nm3,Z=4,d=1.796g/cm3,μ=3.108mm-1,F(000)=1800,R1=0.0430,R2=0.0560.通过己二酸配体羧基氧原子桥联Nd3+形成三维网状结构,4,4’_bpy通过H键的连接存在于孔道中.
The complex of [Nd2 (ad) 3 (H2O) 2] n · n (4) with NdCl3 · xH2O, ad (adipic acid) and 4,4’-bipy was synthesized under hydrothermal conditions , 4’_bpy) were synthesized and characterized by elemental analysis, IR, single crystal X-ray diffraction and fluorescence analysis.The coordination polymers are orthorhombic, Pbcn space group with unit cell parameters of a = 2.2012 ( D = 1.796g / cm3, μ = 3.3770 (15) nm3, d = 1.776 (2) nm and c = 3.108 mm-1, F (000) = 1800, R1 = 0.0430, R2 = 0.0560. The Nd3 + is bridged by the adipic acid ligand carboxy oxygen atom to form a three-dimensional network structure. Hole in the.
