Diethyl 9,10-endo-ethano-9,10-di­hydro­anthracene-11,11-di­carboxyl­ate

The title compound, C22H22O4, possesses normal geometrical parameters and the dihedral angle between the two benzene ring planes is 57.62 (5)°. The crystal packing is controlled by van der Waals forces and a possible C—H⋯O interaction, the latter resulting in a supramolecular C(6) motif.
