Bis-(diphenylmethyl)imidazolium bromide was prepared by reacting excess bromodiphenylmethane and imidazole. The product was characterized by NMR, IR, UV. X-ray crystal diffraction shows that aromaticity of the imidazole ring has been lost, the bromide is not centered in the structure, but rather it is located on one side of the imidazole ring. The structure was compared to similar crystal structures.
