The 1,1-bis(methylthio)-5-(4-chlorophenyl)-1,4-pentadien-3-one compound crystallizes in the space group C2/c with unit cell parameters  Å,  Å,  Å, and . The structure was solved by direct methods and refined to an R-factor of 0.0593. Due to the steric interaction between the two methyl groups, one of the methylthio groups is in cis conformation with C11–C10 double bond and the other is in trans conformation. The cinnamoyl group on the carbonyl carbon atom effects more delocalization of the electrons within the molecule so that the structure is highly conjugated and planar.
