Stressing bismuth : Two monophenyl tetrathiolato Bi V complexes, [BiPh(SR) 4 ], have been prepared upon treating BiPh 3 in toluene/ethanol under reflux conditions with an excess of N‐heterocyclic thiols (see scheme), indicating oxidation of the bismuth center. Crystallization from DMSO over several months leads to reduction of bismuth back to Bi III through protonation of two of the thiolato ligands.
