Crystal structures of three salts of the tri-phenylsulfonium ion.

ABSTRACT: The reactions of tri-phenyl-sulfonium chloride ([TPS][Cl]) with various acids in methanol yield the corresponding salts tri-phenyl-sulfonium triiodide, C₁₈H₁₅S⁺·I₃ ^- or [TPS][I₃] (I), tri-phenyl-sulfonium perchlorate, C₁₈H₁₅S⁺·ClO₄ ^- or [TPS][ClO₄] (II), and tri-phenyl-sulfonium hexa-fluoro-phosphate, C₁₈H₁₅S⁺·PF₆ ^- or [TPS][PF₆] (III), as crystalline products. These crystals were structurally characterized by single-crystal X-ray diffraction. In all three compounds, the sulfur atom in the tri-phenyl-sulfonium cation adopts a distorted trigonal-pyramidal geometry. [TPS][I
