%X During the formation of the title compound, C5H7N2+¡¤C6H2N3O7 , a phenolic proton is transferred to the pyridine N atom. In the crystal structure, the ions are linked by intermolecular N¡ªH...O and N¡ªH...(O,O) hydrogen bonds into layers running parallel to (100). These layers are connected by weak ¦Ð¨C¦Ð stacking interactions between symmetry-related pyridine and picric benzene rings with a centroid¨Ccentroid distance of 3.758 (2)  , forming a three-dimensional network.
