Abstract: The title compound, C21H18O4, has a molecular structure with a rigid polycyclic nucleus, in which an acid anhydride ring bridges the two CH positions of the central ring of anthracene. The 1-methoxyethyl substituent, by contrast, has conformational freedom and adopts an orientation minimizing steric and electronic repulsions with the anhydride group.
