title: 4-Methyl-anilinium 3,5-dinitro-benzoate.
abstract: The crystal structure of the title compound, C(7)H(10)N(+)·C(7)H(3)N(2)O(6) (-), displays N-H⋯O hydrogen bonding between the ammonium groups and the O atoms of the 3,5-dinitro-benzoate anions. Inter-molecular C-H⋯O inter-actions further stabilize the packing. An O atom of each of the nitro groups is disordered over two sites with site occupancy factors of 0.59 (5) and 0.41 (6).
