Abstract

Dithiocarbamic acid reacts in the superacidic media HF/MF 5 (M = As, Sb) under formation of the corresponding salts H 2 NC(SH) 2 + MF 6 - . The colorless compounds are stable in an inert gas atmosphere up to -20 °C. The salts have been characterized by NMR, IR and Raman spectroscopy. Reactions in DF/AsF5 were carried out to obtain D 2 NC(SD) 2 + AsF 6 - in order to confirm the assignments of the observed vibrational modes. Additionally, quantum-chemical calculations of the free cation, (A 2 NC(SA) 2 ) + (A=H, D), and of the (A 2 NC(SA) 2 ( 3 HF)) + unit on the PBE1BPE/6-311G(3df,3pd) level of theory are discussed.
