Protonated Trithiocarbonic Acid ؊ Synthesis, Spectroscopic Characterization and the Crystal Structure of C(SH) 3 ؉ AsF 6 ؊ Rolf Minkwitz,* [a] Frank Neikes, [a] and Ulrike Lohmann [a][ †] Keywords: Carbocations / NMR spectroscopy / Raman spectroscopy / Protonation / Sulfur / Superacidic systems Protonation of trithiocarbonic acid H 2 CS 3 in the superacidic system HF/MF 5 (M = As, Sb) results in the generation and isolation of the extremely water-sensitive salts C(SX) 3 + MF 6 − (M = As, Sb; X = H, D). The slightly yellow salts decompose [a]
