Abstract
In the main molecule of the title compound, C13H11N2O3+·ClO4-, the two aromatic rings are twisted by 56.19 (3)° relative to each other and the nitro group is not coplanar with the benzene ring [36.43 (4)°]. The crystal packing is dominated by infinite aromatic stacks in the a-axis direction. These are formed by the benzene units of the molecule featuring an alternating arrangement, which explains the two different distances of 3.3860 (4) and 3.4907 (4) Å for the aromatic units (these are the perpendicular distances of the centroid of one aromatic ring on the mean plane of the other other aromatic ring). Adjacent stacks are connected by [pi]-[pi] stacking between two pyridinium units [3.5949 (4) Å] and weak C-H...O interactions. The perchlorate anions are accomodated in the lattice voids connected to the cation via weak C-H...O contacts between the O atoms of the anion and various aromatic as well as methyl H atoms.
