| Popis: | In the central fused ring system of the title compound, C51H42O5, 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, molecules are linked by C—H...π interactions, forming a layer parallel to the ab plane. Each molecule acts as a double donor as well as a double acceptor of the C—H...π interactions. Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H...H (61.4%) and C...H/H...C (25.3%) contacts. |
