4-[2-(Pyridin-1-ium-4-yl)eth­yl]pyridin-1-ium bis­(2,6-di­nitro­benzoate)

The asymmetric unit of the title salt, C(12)H(14)N(2) (2+)·2C(7)H(3)N(2)O(6) (−), comprises half a 4-[2-(pyridin-1-ium-4-yl)eth­yl]pyridin-1-ium dication, being disposed about a centre of inversion, and a 2,6-di­nitro­benzoate anion, in a general position. In the anion, the carboxyl­ate group is inclined to the benzene ring [dihedral angle = 85.45 (9)°], whereas near-coplanar and twisted arrangements are found for the nitro groups [O—N—C—C torsion angles = 179.80 (14) and 20.2 (2)°]. In the crystal, three-component aggregates sustained by charge-assisted N(+)—H⋯O(−) hydrogen bonds are found and these are consolidated into a three-dimensional architecture by C—H⋯O and π–π [inter-centroid distances = 3.6796 (14) and 3.7064 (14) Å] inter­actions.
