## Abstract Lanthanide complexes LnL~2~(NO~3~)~3~ **3aβf** are obtained where Ln is La, Ce, Sm, Eu, Er, and Yb and L is the diethyl 2βaminoβ2βoxoethylphosphonate. They were characterized by elemental analysis, IR, and NMR spectroscopy. Monodentate coordination by the phosphoryl group is suggested f

## Preparation of Some Lanthanide Violurate Complexes Violurate complexes of Ce3+, Pr3+, Pr4+, Nd3+, Sm3+, Eu3+, Gd3+, Dy3+, Ho3+, Er3+, and Yb3+ were prepared. The prepared complexes are freely soluble in hot water and dilute mineral acids. Thermal analysis (DTA, DTG, and TGA) show that the solid
