Abstract: Paramagnetic Pr3+ complexes (5a-b) have been prepared by reacting
praseodymium(III) nitrate hexahydrate [Pr(NO3)3.6H2O] (4) with dithiophosphonic
acids [Ar(RO)PS2]- [Ar: p-C6H4OMe, R: Et, nPr] (3a-b) stoichiometrically in THF
solution (5a-b). Compounds were characterized by elemental analysis, FT-IR, [1H, 13C,
31P] NMR spectroscopy and magnetic susceptibility.
Key words: Dithiophosphonate, phosphonodithioic acids, organothio compounds
lanthanide complexes, praseodymium(III) complexes
