5-(4-Chloroanilinomethylene)-2,2-dimethyl-1,3-dioxane-4,6-dione

Abstract

The title compound, C13H12ClNO4, is approximately planar, with a dihedral angle of 8.23 (4)° between the mean plane of the aminomethylene unit and the planar part of the dioxane ring. The dioxane ring has a half-boat conformation, in which the C atom between the dioxane O atoms is −0.464 (8) Å out of the plane of the other five atoms. In the molecule there is an intramolecular N—H...O hydrogen bond, involving the NH H atom and the adjacent dioxane carbonyl O atom. In the crystal, weak intermolecular C—H...O hydrogen-bonding contacts, result in the formation of sheets parallel to the ab plane.
