4-Cyano-1-methylpyridinium bromide

Abstract

In the crystal of the title molecular salt, C7H7N2+·Br−, the cations form inversion dimersviaweak pairwise C—H...N hydrogen bonds; their mean planes are separated by 0.292 (6) Å. Weak C—H...Br interactions involving all of the remaining H atoms tie the cations and anions together into sets of interpenetrating sheets. The title compound is isostructural with its iodide analogue.
