Deskripsi
In the title compound, C5H7N2+·C6H2N3O7−, the 4-aminopyridinium cation is essentially planar (r.m.s. deviation = 0.002 Å). The three nitro groups in the picrate anion are twisted away from the attached benzene ring [dihedral angles = 24.1 (1), 9.3 (3) and 21.4 (1)°]. In the crystal structure, the ions are linked into a three-dimensional network by N—H...O and C—H...O hydrogen bonds.
