In the title salt, C 14 H 14 N 3 + ·NO 3 − , the cation is almost planar (r.m.s. deviation = 0.014 Å), implying significant conjugation of the lone pair of the tertiary amino group N atom with the aromatic ring system. In the extended structure, N—H...O and C—H...O hydrogen bonds link the components into infinite chains of alternating cations and anions propagating along the b -axis direction. Aromatic π–π stacking interactions with centroid–centroid distances of 3.5773 (12) and 3.5889 (12) Å may help to consolidate the packing. Hirshfeld surface analysis revealed that the most important contributions for the crystal packing are from H...H (39.2%), H...O/O...H (31.6%), H...C/C...H (10.3%) and C...C (9.1%) interactions.
