Adducts of bismuth trihalides BiX3 (X = Cl, Br, I) and the PS 3 ligand (PS 3 = P(C6H4-o-CH2SCH3)3) react with HCl to form inorganic/organic hybrids with the general formula [HPS 3 BiX4]2. On the basis of their solid-state structures determined by single-crystal X-ray diffraction, these compounds exhibit discrete bis-zwitterionic assemblies consisting of two phosphonium units [HPS 3 ]+ linked to a central dibismuthate core [Bi2X8]2- via S→Bi dative interactions. Remarkably, the phosphorus center of the PS 3 ligand undergoes protona
