5,5′-[(2,4-Dichlorophenyl)methylene]bis(2,2-dimethyl-1,3-dioxane-4,6-dione)

Abstract

The title compound, C19H18Cl2O8, was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 2,4-dichlorobenzaldehyde in ethanol. The two 1,3-dioxane rings exhibit boat conformations. In the crystal, molecules are linked by weak intermolecular C—H...O and C—H...Cl hydrogen bonds, forming chains parallel to the a axis.
