4-tert-Butyl-pyridinium picrate

Abstract

In the title compound, C9H14N+· C6H2N3O7-, the three nitro groups of the picrate anion are twisted out of the plane of the attached benzene ring; the dihedral angles are 32.8 (2), 10.5 (4) and 12.3 (4)°. The pyridinium cations and picrate anions are linked via bifurcated N - H⋯(O,O) hydrogen bonds. The ionic pairs are linked into a ribbon-like structure along [101] by C - H⋯O hydrogen bonds.
