8-Phenyl-16-thiapentacyclo[6.6.5.0 1,18 .0 2,7 .0 9,14 ]nonadeca-2,4,6,9,11,13,18-heptaene

In the title compound, C24H18S, the dihedral angles between the phenyl ring and the two benzene rings of the anthracene moiety are 51.92 (9) and 68.24 (9)°, whereas the dihedral angle between the two anthracene benzene rings is 120.13 (9)°. The three non-aromatic six-membered rings are in boat conformations, while the five-membered ring has an envelope conformation on the S atom. In the crystal, there are three C-H...π interactions, which facilitate the packing of the molecules.
