Crystal Structure of 1,3-Dimethylimidazolium Bis(fluorosulfonyl)amide: Unexpectedly High Melting Point Arising from Polydentate Hydrogen Bonding
1,3-Dimethylimidazolium bis(fluorosulfonyl)amide, [C1mim]FSA, is an ionic liquid with a lower viscosity than the bis(trifluoromethanesulfonyl)amide salt, [C1mim]NTf2, but with a higher melting poin...
