Abstract: In the title compound, C20H17NO3 (alternative name: N-hy­droxy-9,10-dimethyl-9,10-ethano­anthracene-11,12-dicarboximide), the rigid ethano­anthracene-dicarboximide moiety has a roof-shaped geometry, the inter­planar angle between the two terminal phenyl rings being 124.9 (6)°. In the crystal, mol­ecules are linked via O-H...O hydrogen bonds, forming chains along [010]. C-H...O and C-H...[pi] inter­actions link adjacent chains, leading to the formation of a three-dimensional structure.
