Abstract

The crystal structure of SCl3 +AsF6 - is reported. The mean S-Cl stretching frequency ν̄ of the SCl3 + cations, weighted according to the degree of degeneration, in the different SCl3 +X- salts is directly proportional to the mean S-CI distance r̄scl, the force constant fSCl and the sulfur. . . anion distance (Cl3S+. . . X-). That SCI3 +Cl- should be isostructural with PCl4 - , the large variation in the S-CI stretching frequencies in the SCl3 +X- salts is due to cation-anion interaction forces
