J. Fuller et al., STRUCTURE OF 1-ETHYL-3-METHYLIMIDAZOLIUM HEXAFLUOROPHOSPHATE - MODEL FOR ROOM-TEMPERATURE MOLTEN-SALTS, Journal of the Chemical Society, Chemical Communications, (3), 1994, pp. 299-300
The crystal structure of 1-ethyl-3-methylimidazolium (EMI(+)) hexafluo
rophosphate consists of interionic interactions dominated by cation-an
ion coulombic forces with minimal hydrogen bonding and serves as a mod
el for EMI(+) room temperature molten salts containing weakly complexi
ng anions.
