The title compound, C15H11N2+·HN2O6−, crystallizes in the monoclinic space group C2/c with four mol­ecules in the unit cell. The planar 9-cyano-10-methyl­acridinium cations lie on crystallographic twofold axes and are arranged in layers, almost perpendicular to the ac plane, in such a way that neighbouring mol­ecules are positioned in a `head-to-tail' manner. These cations and the hydrogen dinitrate anions are linked through C—H⋯O interactions involving four of the six O atoms of the anion and the H atoms attached to the C atoms of the acridine moiety in ring positions 2 and 4. The H atom of the hydrogen dinitrate anion appears to be located on the centre of inversion relating two of the four O atoms engaged in the above-mentioned C—H⋯O interactions. In this way, columns of either anions or cations running along the c axis are held in place by the network of C—H⋯O interactions, forming a relatively compact crystal lattice.
