1-Carboxymethyl-3-octylimidazolium bromide
Abstract
In the title compound, C13H23N2O2+·Br−, the octyl chain has an all-trans conformation. In the crystal, the cations are linked by C—H...O bonds into a zigzag chain along the b axis. The bromide anions further link the chains via C—H...Br interactions into a two-dimensional array parallel to the ab plane. An O—H...Br interaction is also observed.
