2,2-Dimethyl-5-[(3-nitro-anilino)methyl-ene]-1,3-dioxane-4,6-dione.

ABSTRACT: The benzene ring of the title compound, C(13)H(12)N(2)O(6), is twisted away from the planes of the amino-methyl-ene unit and the dioxane ring by 30.13?(4) and 35.89?(4)°, respectively. The dioxane ring exhibits a half-boat conformation, in which the C atom between the dioxane O atoms is 0.553?(8)?Å out-of-plane. An intra-molecular N-H?O hydrogen bond stabilizes the conformation of the dioxane ring with the amino-methyl-ene group [the dihedral angle between the mean planes of the dioxane ring and the amino-methyl-ene group is 11.61?(4)°]. In the crystal, a three-dimensional framework is built via weak inter-molecular N-H?O and C-H?O inter-actions.
