Experimental Crystal data

R factor = 0.042; wR factor = 0.138; data-to-parameter ratio = 16.6. 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 conforma-tions, while the five-membered ring has an envelope conformation on the S atom. In the crystal, there are three C—H interactions, which facilitate the packing of the molecules. Related literature For background to dibenzobarrelene dervatives and thei
