Synthesis and Characterization of Tris[P,P,P',P'-Tetramethylimidobis (Phosphine Sulfido)S,S'] Bismuth(III)
Chemistry and Biochemistry
Complexes of tetramethylimidodithiodiphosphinate, [(CH3)2P(S)N(S)P(CH3)2]-, are relatively rare in the literature. The bis-complexes of Co(II), Ni(II), and Fe(II) as well as a few other divalent cations have been reported and the crystal structure of the Fe(II) and Ni(II) complexes have been Determined. A bis-complex of Pb(II) has also been reported. The tetraphenylimidodithiodiphosphinate ligand has gained a great deal more attention with several bis-and tris-complexes having been reported for both main group and transition elements. A crystal structure of the free protonated ligand has been determined as well.
