title: 5-(4-Chloro-anilinomethyl-ene)-2,2-dimethyl-1,3-dioxane-4,6-dione.
abstract: The title compound, C(13)H(12)ClNO(4), is approximately planar, with a dihedral angle of 8.23 (4)° between the mean plane of the amino-methyl-ene 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 mol-ecule there is an intra-molecular 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.
