The aim of this thesis was to synthesize a ternary samarium complexes in which three pyrithionate anions are coordinated to the lanthanide ion, together with one or two neutral ligands. The procedure was based on the sequential binding of the different ligands. In this multi-step stythesis, first a precursor was prepared from samarium(III) nitrate hexahydrate and triphenylphosphine oxide (tppo). The synthesized product was then used in a reaction with pyrithione and sodium metoxide. In the final step, I wanted to replace the remaining two molecules of triphenylphosphine oxide with a stronger, bidentately bound ligand, 1,10-phenanthroline (phen). Final complex was characterized by nuclear magnetic resonance (NMR), mass spectrometry, CHN elemental analysis and IR spectroscopy.
