1,3-Bis(2-cyanobenzyl)imidazolium bromide

Abstract

In the title salt, C19H15N4+·Br−, the central imidazole ring makes dihedral angles of 83.1 (2) and 87.6 (2)° with the terminal benzene rings. The dihedral angle between the terminal benzene rings is 6.77 (19)°; the cyanide substituents have an anti orientation. In the crystal, the cations and anions are linked via C—H...N and C—H...Br hydrogen bonds, forming sheets lying parallel to the ac plane.
