Summary A range of low melting salts of the bis(trifluoromethanesulfonyl)amide (TFSA) anion with hindered organic cations (N-methyl-1-methylpyrrolinium, N,N-dimethylpyrrolidinium, N,N,N,-trimethylammonium, and N,N,N,N-tetrakis(n-propyl)ammonium) have been crystallized. Single-crystal X-ray diffraction data show these materials to consist of discrete ions with only weak C−H···O (or for Me3NH N−H···O) contacts between the constituent atoms of the cations and anions close to the limits of van der Waals separations. Consequently, the observed physical properties of these materials presumably result from the diffuse negative charge on the TFSA anion and inefficient packing of these large and irregularly shaped ions.
