2-Amino-4-methyl-pyridinium 4-nitro-benzoate

In the title salt, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-), the nitro group of the 4-nitro-benzoate anion is twisted by 7.66 (10)° from the attached ring. In the crystal structure, the 2-amino-4-methyl-pyridinium cations and 4-nitro-benzoate anions are linked via a pair of N-H⋯O hydrogen bonds to form a ribbon-like structure along the c axis. The ribbons are crosslinked into a three-dimensional framework by C-H⋯O hydrogen bonds.
