	abstract = {{The N4O3 tripodal aminomethylene phosphinato ligand tris(4-phenylphosphinato-3-methyl-3-azabutyl)amine (H-3-ppma) forms mono- and bis(ligand) complexes with lanthanide(III) metal ions Ln when Ln = Sm-Lu. The formation constants of the Lu (log beta(1) = 1.79, log beta(2) = 4.40) and the Yb (log beta(1) = 2.25, log beta(2) = 4.42) complexes were determined at pH = 1.5 using an unusual P-31 NMR spectroscopic method. The molecular structure of the lutetium complex [Lu(H(3)ppma)(2)](NO3)(3) . 3H(2)O (C60H96LuN11O24P6) was solved by X-ray methods; it crystallizes in the trigonal space group R(3) over barc$, with a = 19.060(1) Angstrom},
