三甘双酰氮甲基苯胺稀土高氯酸盐配合物的合成及表征

Synthesis and characterization of the complexes of lanthanide perchlorates with N, N'-dimethyl-N, N'-diphenyl-3, 6-dioxaoctane diamide

在非水介质中由轻稀土高氯酸盐与配体三甘双酰氮甲基苯胺(L)形成的6种具有稀土特征颜色的固体配合物,通式为[Ln(L)2(H2O)n](ClO4)3(Ln=La,Pr,Nd,Sm时,n=2;Ln=Eu,Tb时,n=1;不包括Pm),在这些新配合物中,配体L表现为四齿配位行为.

Lanthanide perchlorate complexes with the ligand N, N'-dimethyl-N, N'-diphenyl-3, 6-dioxaoctane diamide(L) have been prepared in non-aqueous media and they can be expressed with the general formula [Ln(L)2(H2O)n] (ClO4)3(for Ln=La, Pr, Nd, Sm, n=2; for Ln=Eu, Tb, n=1) in all the complexes, the ligand shows quadridentate behavior.
