Crystal structure of di-methyl-formamidium bis-(tri-fluoro-methane-sulfon-yl)amide: an ionic liquid.

ABSTRACT: At 100 K, the title mol-ecular salt, C₃H₈NO⁺·C₂F₆NO₄S₂^-, has ortho-rhom-bic (P2₁2₁2₁) symmetry; the amino H atom of bis-(tri-fluoro-methane-sulfon-yl)amine (HNTf₂) was transferred to the basic O atom of di-methyl-formamide (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 inter-action, generating an R₂²(7) loop. A further very weak C-H⋯O inter-action generates an [001] chain.
