[(Di-methyl-amino)-meth-yl]di-methyl-aza-nium bis--(tri-fluoro-methane-sulfon-yl)amide

摘要

The title mol-ecular salt, C5H15N2+·C2F6NO4S2?, was obtained by a proton transfer reaction between bis-(tri-fluoro-methane-sulfon-yl)amine and bis-(di-methyl-amino)-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).
