In the central fused ring system of the title compound, C<sub>51</sub>H<sub>42</sub>O<sub>5</sub>, all of the five-membered rings are in an envelope conformation. The dihedral angle between the two benzene rings in the fused ring system is 74.66 (7)°. In the crystal, mol-ecules are linked by C-H⋯π inter-actions, forming a layer parallel to the <i>ab</i> plane. Each mol-ecule acts as a double donor as well as a double acceptor of the C-H⋯π inter-actions. Hirshfeld surface analysis and two-dimensi ...[more]
