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-HO hydrogen bonds, forming chains along . C-HO and C-H interactions link adjacent chains, leading to the formation of a three-dimensional structure.
