The reactions of (2-methyl-4-oxopent-2-yl)diphenylphosphine oxide (L) with uranyl and neodymium nitrates afforded complexes with compositions M: L = 1: 2 and 1: 3. These complexes were characterized by X-ray diffraction, IR spectroscopy, and elemental analysis. In the solid complexes, phosphine oxide L has a variable denticity. Studies by 1H and 31P NMR and IR spectroscopy showed that in chloroform, the mononuclear complexes [UO2(O-L)2-(O,O-NO3)2], [Nd(O-L)2(O,O-NO3)3] and [Nd(O-L)3(O,O-NO3)3] are neutral, and the ligand molecules are coordinated to the metal cation through the phosphoryl oxygen atom.
