Abstract

The asymmetric unit of the title compound, C20H22O10Cl2, consists of a 6-{[(benz­yloxy)carbon­yl]­oxy}group and two chloro­acetate groups bonded to a 2-methyl­hexa­hydro­pyrano[3,2-d][1,3]dioxin group at the carbon 1,2 and 3 positions, respectively, of a pyrano ring fused to a dioxin ring. The dihedral angle between the mean planes of the dioxin and benzyl rings is 42.2 (2)°. An extensive array of weak inter­molecular C—H⋯O hydrogen bonds links the mol­ecules into chains along [011]. Additional weak inter­molecular C—H⋯π inter­actions occur between C—H atoms of the dioxin and benzyl rings and a nearby benzene ring. A MOPAC geometry optimization calculation in vacuo revealed that the dihedral angle between the mean planes of the dioxin and benzyl rings increased by 24.42 to 66.64°, suggesting that the weak inter­molecular hydrogen-bonding inter­actions, in coord­ination with weak C—H⋯π inter­actions, influence the geometry of the resultant crystalline species and help to stabilize the crystal packing.
