Abstract
In the title complex, C13H11N3O6, it is observed that the very strong NHO [N⋯sO 2.525(2) Å] holds the molecules of 3,5-dinitrobenzoic acid and 4-methylpyridine together, and that the hydrogen atom is centered between the hydrogen donor and acceptor in that hydrogen bond. The heterocyclic moiety appears as an intermediate between pyridine and pyridinium, while the benzoic acid between carboxylate and carboxylic group. The title complex is further stabilized by CHO hydrogen bonds and π–π interaction.
