title: 8-Chloro-methyl-5-(2,5-dioxooxolan-3-yl)-3,3a,4,5-tetra-hydro-1H-naphtho-[1,2-c]furan-1,3-dione.
abstract: The title compound, C17H13ClO6, is an asymmetric alicyclic dianhydride containing a chloro-methyl-substituted tetra-hydro-naphthalene moiety. The cyclo-hexene ring in the tetra-hydro-naphthalene 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, mol-ecules are connected by weak C-H⋯O inter-actions, forming a three-dimensional supramolecular structure.
