摘要：

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 center dot center dot center dot O and C-H center dot center dot center dot Cl hydrogen bonds, forming chains parallel to the a axis.
