title: Crystal structure of 1,3-bis-{[4-(acetyl-sulfanyl)phenyl]ethynyl}azulene.
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 acetyl-sulfanyl groups are 59.60 (10) and 84.79 (10)°. The expected π-π stacking inter-actions are not observed in the crystal structure; instead, the packing features C-H⋯O hydrogen bonds, which link the mol-ecules into C(12) [010] chains, which are supported by weak C-H⋯π contacts.
