rac-3,9-Bis(3-chlorophenyl)-2,4,8,10-tetraoxaspiro[5.5]undecane

In the title compound, C19H18Cl2O4, the two non-planar six-membered heterocycles passing through the spiro-C atom both adopt chair conformations, and the dihedral angle between the two benzene rings is 7.2 (1)°. In the crystal, the enantiomers with R and S configurations are generated by the symmetry elements of the centrosymmetric space group, forming a racemic crystal. Intermolecular C—H...π and weak C—H...O interactions link the molecules in the crystal structure.
