Abstract
The structures of HN(SO2R)(2), R=E CF3 are formed by molecules linked by hydrogen bonds to infinite chains. While KN(SO2F)(2) is composed of alternating cations and anions, HN(SO2CF3)(2) exhibits a pronounced l ayer structure. In the acids, the substituents -R are in trans configu ration being on the opposite sides of the plane defined by S-N-S bonds but in the salts the cis configuration with both substituents on the same side of the S-N-S plane is preferred, probably due to numerous me tal-anion interactions.
