[(Dimethylamino)methyl]dimethylazanium bis(trifluoromethanesulfonyl)amide

Abstract

The title molecular salt, C5H15N2 +·C2F6NO4S2 −, was obtained by a proton transfer reaction between bis(trifluoromethanesulfonyl)amine and bis(dimethylamino)methane. In the crystal, the ions are linked by N—H...O=S hydrogen bonds, and these units are linked by C—H...O hydrogen bonds, forming sheets parallel to the bc plane. The crystal was refined as a non-merohedral twin with a BASF factor of 0.316 (1).
