Abstract: The title compound, C17H13ClO6, is an asymmetric alicyclic dianhydride containing a chloromethyl-substituted tetrahydronaphthalene moiety. The cyclohexene ring in the tetrahydronaphthalene moiety exhibits an envelope conformation with the tertiary C atom as the flap The dihedral angle between the two anhydride rings is 79.96 (6)°, while those between the benzene ring and the non-fused and fused anhydride rings are 71.03 (5) and 42.57 (7)°, respectively. In the crystal, molecules are connected by weak C-HO interactions, forming a three-dimensional supramolecular structure.
