Monoorganobismuth(III) thiocarboxylates: Synthesis, characterization and crystal structures of [PhBi(SOCR)₂] (R = Ph or Me)

34-38The reactions of methylbismuth dichloride in the presence of triethylamine and triphenylbismuth with thiocarboxylic acids, RC(O)SH (R = Ph or Me) in 1:2 ratio in benzene affords monoorganobismuth thiocarboxylates, [R’Bi(SOCR)2] [R’ = Me, Ph; R = Ph or Me]. These complexes have been characterized by elemental analyses and NMR (1H, 13C{1H}) spectroscopy. Molecular structures of [PhBi(SOCR)2] [R = Ph or Me] have been established by single crystal X-ray analyses. The complexes are associated in the solid state acquiring either pentagonal bipyramidal (when R = Me) or distorted octahedral (when R = Ph) configuration around bismuth atom
