摘要：

Solvated solvents: Water molecules interact with the imidazolium cation and [BF4]ion (see picture) of the molten ionic-liquid salt 1-n-butyl-3-methylimidazolium tetrafluoroborate. Evidence for short C-H ⋯ O and C-H ⋯ F interactions is provided by 1H{ 1H} and 1H{19F} NMR spectroscopy nuclear Overhauser enhancements.
