In the title salt, C(20)H(22)N(2) (2+)·2C(12)H(4)N(4) (-), 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 inter-actions, with centroid-centroid separations of 3.874 (4) Å. The crystal packing is stabilized by inter-columnar C-H⋯N hydrogen bonds. ...[more]
