摘要
本文以间苯二甲亚胺双 (苯并 - 1 5 -冠 - 5)为配体 ,合成了十三种双冠醚稀土苦味酸盐配合物 ,Ln(Pic) 3·L·nH2 O[Ln=La ,n=5 ;Ln =Pr -Yb ,Y ,n =3 ;L =m -C6 H4(N =CH -B - 1 5-C - 5) 2 ] .通过元素分析、红外光谱、紫外光谱和差热—热重分析 。
Thirteen novel complexes of rare earth picrates with Schiff base type bis crown ethers having the formula of Ln(Pic) 3·L·nH 2O[Ln=La,n=5;Ln=Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Y,n=3;L=m-C 6H 4(N=CHB-15-C-5) 2]have been synthesized in acetonitrile isopropanol chloroform.Their composition and properties have been studied by elementary analysis,infrared and ultraviolet spectra,as well as thermogravimetric (TG) and differential thermal analysis.(DTG).
