2,2-Dimethyl-5-[(2-nitroanilino)methylidene]-1,3-dioxane-4,6-dione

Abstract

The crystal of the title compound, C13H12N2O6, contains a bifurcated intramolecular hydrogen bond between the N—H group and one of the O atoms from both the nitro group and the dioxane-4,6-dione moiety. In addition, molecules are linked by a series of intermolecular C—H...O secondary interactions. The dihedral angles between the benzene ring and the nitro group and the conjugated part of the dioxane-4,6-dione moiety are 19.1 (2) and 17.89 (7)°, respectively.
