Abstract

A new tripodal O-donor ligand, tris(2-N,N-dibutylcarbamoylmethoxyphenyl)phosphine oxide (L), was synthesized. This potentially tetradentate ligand L exhibits variable denticity upon complexation with UO₂(NO₃)₂, Nd(NO₃)₃, and Lu(NO₃)₃. The complexes were studied by elemental analysis, IR, and ¹H, ¹³C, and ³¹P NMR spectroscopy.
