Abstract
The title compound crystallizes in space group Pbca with four molecules in the unit cell.
The complete molecule of the title compound, C28H30O4, is generated by a crystallographic centre of symmetry and the ester moiety is twisted away from the fused-ring plane by 28.03 (8)° due to steric repulsion. In the crystal, a weak C—H⋯O hydrogen bond links the molecules into (001) sheets.
