The title molecular salt, C6H8N+center dot C6H2N3O7-(systematic name: 3-methylpyridinium 2,4,6-trinitrophenolate), crystallizes in the triclinic space group P (1) over bar. The crystal structure of the monoclinic polymorph (space group P2(1)/n) has been reported [Stilinovic & Kaitner (2011). Cryst. Growth Des. 11, 4110-4119]. In the crystal, the anion and cation are linked via bifurcated N-H center dot center dot center dot(O,O) hydrogen bonds, enclosing an R-1(2) (6) graph-set motif. These units are linked via C-H center dot center dot center dot O hydrogen bonds, forming a three-dimensional framework. Within the framework there are pi-pi interactions present, involving inversion-related picrate anions and inversion-related pyridinium cations, with inter-centroid distances of 3.7389 (14) and 3.560 (2) angstrom, respectively.
