title: 2,4,6-Trimethyl-pyridinium 4-nitro-benzoate-4-nitro-benzoic acid (1/1).
abstract: The asymmetric unit of the title co-crystal, C(8)H(12)N(+)·C(7)H(4)NO(4) (-)·C(7)H(5)NO(4), contains two cations, two anions and two neutral 4-nitro-benzoic acid mol-ecules. In the crystal, O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds connect the ions and mol-ecules, forming a three-dimensional network.
