Dibismuthates as Linking Units for Bis-Zwitterions and Coordination Polymers.

ABSTRACT: Adducts of bismuth trihalides BiX₃ (X = Cl, Br, I) and the PS₃ ligand (PS₃ = P(C₆H₄-o-CH₂SCH₃)₃) react with HCl to form inorganic/organic hybrids with the general formula [HPS₃BiX₄]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 [HPS₃]⁺ linked to a central dibismuthate core [Bi₂X₈]^2- via S→Bi dative interactions. Remarkably, the phosphorus center of the PS₃ ligand undergoes protonation wi
