title: 2-Methyl-pyridinium 5-(2,4-dinitro-phen-yl)-1,3-dimethyl-barbiturate.
abstract: In the title mol-ecular salt [systematic name: 2-methyl-pyridinium 5-(2,4-dinitro-phen-yl)-1,3-dimethyl-2,6-dioxo-1,2,3,6-tetra-hydro-pyrimidin-4-olate], C(6)H(8)N(+)·C(12)H(9)N(4)O(7) (-), the cation and anion are linked a through strong N-H⋯O hydrogen bond. In the crystal, C-H⋯O inter-actions link the ions, generating a chain along [010].
