【 摘 要 】

At 100 K, the title mol­ecular salt, C3H8NO+·C2F6NO4S2−, has ortho­rhom­bic (P212121) symmetry; the amino H atom of bis­(tri­fluoro­methane­sulfon­yl)amine (HNTf2) was transferred to the basic O atom of di­methyl­formamide (DMF) when the ionic liquid components were mixed. The structure displays an O—H⋯N hydrogen bond, which links the cation to the anion, which is reinforced by a non-conventional C—H⋯O inter­action, generating an R22(7) loop. A further very weak C—H⋯O inter­action generates an [001] chain.
