Abstract

The structure of dimethylformamidium bis(trifluoromethanesulfonyl)amide (1), C2F6NO4S2·C3H8NO, at 100 K has orthorhombic (P212121) symmetry. The amino proton of bis(trifluoromethanesulfonyl)amine (HNTf2) is transferred to the basic amino group of dimethylformamide (DMF). The structure displays N—H···O hydrogen bonding. This hydrogen bond network allows it to facilitate fast proton movement. The structure also features a non-conventional C—H···O hydrogen bond.
