N,N′,N′′-Triphenyl­guanidinium 5-nitro-2,4-dioxo-1,2,3,4-tetra­hydro­pyrimidin-1-ide

In the title compound, C(19)H(18)N(3) (+.)C(4)H(2)N(3)O(4) (−), the dihedral angles between the phenyl rings and the plane defined by the central guanidinium fragment are in the range 41.3 (1)–66.6 (1)°. The pyrimidine ring of the anion is distorted towards a boat conformation and the nitro group is...

Descripción
Sumario:In the title compound, C(19)H(18)N(3) (+.)C(4)H(2)N(3)O(4) (−), the dihedral angles between the phenyl rings and the plane defined by the central guanidinium fragment are in the range 41.3 (1)–66.6 (1)°. The pyrimidine ring of the anion is distorted towards a boat conformation and the nitro group is rotated 11.4 (2)° out of the uracil plane. Hydrogen bonds assemble the ions in infinite helical chains along the b axis.
