Abstract

Lanthanide complexes LnL~2~(NO~3~)~3~ 3a–f are obtained where Ln is La, Ce, Sm, Eu, Er, and Yb and L is the diethyl 2‐amino‐2‐oxoethylphosphonate. They were characterized by elemental analysis, IR, and NMR spectroscopy. Monodentate coordination by the phosphoryl group is suggested for the ligand on the basis of the spectral data. The stabilization is achieved by including a molecule of the solvent in the complexes 3a–d. © 2003 Wiley Periodicals, Inc.
