2-Cyano-1-methylpyridinium nitrate

Abstract

In the title compound, C(7)H(7)N(2) (+)·NO(3) (-), all atoms except the methyl H atoms lie on a crystallographic mirror plane. The inter-layer distance, including that between aligned N atoms from alternating cations and anions in adjacent layers, is exceptionally short at 3.055 (1) Å. Two-dimensional C-H⋯O hydrogen-bonded networks link cations to anions, while C-H⋯N inter-actions link cations within each layer. Anion-π inter-actions with the cations assist in binding the layers together.
