N,N-Diethyl-anilinium 2,4-dioxo-5-(2,4,6-trinitro-phen-yl)-1,2,3,4-tetra-hydro-pyrimi-din-6-olate.
In the crystal structure of the title mol-ecular 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 intra-moleculer N-H⋯O hydrogen bonds are observed in the anion. The dihedral angle between 2,4,6-trinitro-phenyl and barbiturate rings is 53.6 (2)°. The N,N-diethyl-amine substituent is disordered and was modeled as two geometrically equivalent conformers with occupancies of 0.737 (2) and 0.273 (2).
