Abstract The trifunctional ligand, 2, 6-bis (diphenylphosphorylmethyl)-4-methylphenol (L 2), forms complexes with cerium (III) nitrate having a ligand to metal ratio of 1: 1, 2: 1, and 3: 1. The structures of these complexes in the solid state and in solution were studied by X-ray diffraction, IR and NMR (1 H and 31 P) spectroscopy, and conformational analysis (molecular mechanics). The 2: 1 complexes of L 2 with lanthanum (III) and neodymium (III) ...
