N,N-Diethyl­anilinium 2,4-dioxo-5-(2,4,6-trinitro­phen­yl)-1,2,3,4-tetra­hydro­pyrimi­din-6-olate

In the crystal structure of the title mol­ecular salt, C(10)H(16)N(+)·C(10)H(4)N(5)O(9) (−), the components are linked through a N—H⋯O hydrogen bonds. R (2) (2)(8) ring motifs are formed between inversion-related barbiturate residues. Two intra­moleculer N—H⋯O hydrogen bonds are observed in the anion. The dihedral angle between 2,4,6-trinitro­phenyl and barbiturate rings is 53.6 (2)°. The N,N-diethyl­amine substituent is disordered and was modeled as two geometrically equivalent conformers with occupancies of 0.737 (2) and 0.273 (2).
