In the title compound, C 10 H 10 N 4 O 4 , the triazine ring is nearly planar. The 1,3-dioxane-4,6-dione ring exhibits a half-chair conformation. The molecule is disordered and the structure has been refined using a split model.
The orientations of NH 2 and CH 3 of the title compound, C 6 H 9 NO 2 , are mainly stabilized by N-HÁ Á ÁO and C-HÁ Á ÁO intramolecular hydrogen bonds, as well as intermolecular N-HÁ Á ÁO and C-HÁ Á ÁO hydrogen bonds.
