Abstract The preparation of the adducts of lanthanide isothiocyanates and N,N-dimethyl-diphenylphosphinamide (DDPA) having the general formulas Ln (NCS) 3 ·4DDPA (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd) and Ln(NCS) 3 ·3DDPA (Ln = Tb, Dy, Ho, Er, Tm, Yb, Lu, Y) is described. Infrared spectra indicate coordination of the NCS − ion through the nitrogen and of the DDPA through the phosphoryl oxygen. Electrolytic
摘要制备了通式为Ln(NCS)3·4DDPA(Ln = La,Ce,Pr,Nd,Sm,Eu,Gd)和Ln的镧系元素异硫氰酸酯和N,N-二甲基-二苯基次膦酰胺(DDPA)加合物(NCS)3·3DDPA(Ln = Tb,Dy,Ho,Er,Tm,Yb,Lu,Y)被描述。红外光谱表明通过氮的NCS-离子和通过磷酰氧的DDPA的配位。乙腈和硝基甲烷中的电导数据表明,这些化合物在这些溶剂中为非电解质。X射线数据表明存在两个同构的物质系列,分别对应于含有四个和三个DDPA的化合物。
