Crystal structure of di­methyl 5-(4-ethyl­phen­yl)-4-[(4-ethyl­phen­yl)ethyn­yl]-6,11-di­phenyl-1,3,6,11-tetra­hydro-2H-6,11-ep­­oxy­cyclo­penta­[a]anthracene-2,2-di­carboxyl­ate

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.
