Abstract

In the title compound, C(21)H(20)Br(2)O(2)S, prepared by the reaction of 1,9-bis-(4-bromo-phen-yl)nona-2,7-diene-1,9-dione with sodium sulfide nona-hydrate in acetonitrile, the six-membered thio-pyran ring has a chair conformation while the H atoms ortho to the S atom adopt a cis configuration. The dihedral angle between the two benzene rings is 2.59 (8)°.
