Crystal Structure of 2,3-Dimethyl-1-propylimidazolium Bromide

Abstract

The title compound, C₈H₁₅BrN₂, crystallizes in the orthorhombic space group P2₁2₁2₁ with cell parameters a = 6.946(2), b = 11.688(4), c = 12.627(4)Å. Besides the C6 methylene protons, the C3 and C4 protons form hydrogen bonds with the bromide anion, which could be the result of substituting a methyl-group for the C1 proton. These hydrogen bonds should be critical in stabilizing the molecular structure of the title compound.
