2,2-Dimethyl-5-{[(4-nitro-phen-yl)amino]-methyl-idene}-1,3-dioxane-4,6-dione. | LitMetric
In the title compound, C(13)H(12)N(2)O(6), the dihedral angle between the benzene ring and the amino-methyl-ene unit is 5.42 (16)°, while the angle between the amino-methyl-ene unit and the dioxane ring is 3.06 (43)°. The dioxane ring shows a half-boat conformation, in which the C atom between the dioxane ring O atoms is 0.464 (10) Å out of the plane. An intra-molecular N-H⋯O hydrogen bond stabilizes the mol-ecular conformation. In the crystal, a three-dimensional framework is built up via inter-molecular N-H⋯O hydrogen bonds.
