| description | In the title salt, C20H22N22+·2C12H4N4−, the cations and anions stack along the b axis into segregated columns. In the cation, which has a crystallographically imposed centre of symmetry, the dihedral angle between the benzene and pyridine rings is 89.14 (4)°. Centrosymmetrically related anions form dimers by π–π stacking interactions, with centroid–centroid separations of 3.874 (4) Å. The crystal packing is stabilized by intercolumnar C—H...N hydrogen bonds. |
