Protonated O,S-dimethyl dithiocarbonate - Synthesis, spectroscopic characterization and the crystal structure of (CH3O)(CH3S)CSH+SbF6-

Dithiocarbonic acid O,S-dimethyl ester reacts with the super acidic system HF/MF5 (M = As, Sb) to form (MeO)(MeS)CSX+MF6- (M = As, Sb; X = H, D), (MeO )(MeS)CSH+SbF6- crystallizes in the monoclinic space group P2(1)/n (No. 14) with a = 8.634(2) Angstrom, b = 9.521(3) Angstrom, c = 12.509(4) Angstrom, beta = 97.39(2)degrees and 4 formula units per cell. The reaction of O,S-d imethyl dithiocarbonate with the super acidic systems XF/MF5 (X = H, D; M = As, Sb) is discussed with regard to the formation of the salts, and Raman, IR, H-1 NMR, and C-13 NMR spectra of (MeO)(MeS)CSX+MF6- (M = As, Sb; X = H , D) are reported.
