Abstract
In the title compound, C30H20O2S2, the dihedral angles between the central azulene ring system (r.m.s. deviation = 0.039 Å) and the pendant benzene rings are 28.96 (7) and 55.15 (7)°. The dihedral angles between the benzene rings and their attached acetylsulfanyl groups are 59.60 (10) and 84.79 (10)°. The expected π–π stacking interactions are not observed in the crystal structure; instead, the packing features C—H⋯O hydrogen bonds, which link the molecules into C(12) [010] chains, which are supported by weak C—H⋯π contacts.
