摘要
合成了一种新的稀土配合物Nd(Phen)2(NO3)3,化学式为C24H16N7NdO9,Mr=690.68,晶体属于单斜晶系,Cc空间群,晶胞参数:a=1.11975(17)nm,b=1.8073(3)nm,c=1.3095(2)nm,β=100.584(3)°,V=2.6051(7)nm3,Z=4,Dc=1.761g/cm3,F(000)=1364,μ=2.060mm-1,λ(MoKα)=0.071073nm,R=0.0187和wR=0.0300,数据显示配位多面体为一个变形的反四方棱柱配合物,钕的配位数为十配位,4个氮原子和6个氧原子参与配位,4个Nd—N键长在0.2584(4)nm到0.2652nm之间,6个Nd—O键长则在0.2496(3)nm到0.2603nm之间.
A new Nd(Ⅲ) complex,Nd(Phen)_2(NO_3)_3 (Phen=1,10-phenanthroline) was synthesized,and its crystal structure was determined by single crystal X-ray diffraction.Nd(Phen)_2(NO_3)_3(M_r=690.68) belongs to monoclinic crystal system,space group is C_c with crystal cell parameters:a=1.197 5(17) nm,b=1.807 3(3) nm,c=1.309 5(2) nm,β=100.584(3)°,V=2.605 1(7) nm^3,Z=4,(D_c=)1.761 g/cm^3,F(000)=1 364,μ=2.060 mm^(-1),λ_((MoKα))=0.071 073 nm,R=0.018 7 and wR=0.030 0 for 5 291 observed reflections with I>2σ(I).The Nd(Ⅲ) ion is coordinated in a distorted bicapped square-antiprism geometry and surrounded by four nitrogen atoms from two phen ligands and six oxygen atoms from three NO^-_3 anions,respectively.The Nd-N bond lengths are in the range of 0.258 4(4) nm to 0.265 2 nm and the Nd-O bond lengths range from 0.249 6(3) nm to 0.260 3 nm.The compound is characterized by IR,elemental analysis.
