1-Benzyl­sulfanyl-2-[(2-chloro­phen­yl)diazen­yl]benzene

The title compound, C(19)H(15)ClN(2)S, a divalent organosulfur compound belonging to the class of ortho-mercaptoazo compounds, is non-ionic in nature. The azo group in the mol­ecule is moved away from the S atom to attain the stable trans-azo configuration. Here the S atom is not electron deficient, so no intra­molecular N⋯S inter­action exists. Due to steric reasons, the mol­ecule is non-planar: the chlorophenyl and benzyl rings are oriented at dihedral angles of 3.21 (8) and 78.18 (5)°, respectively, with respect to the thiophenyl ring. There are no hydrogen bonds and the crystal structure is stabilized by van der Waals inter­actions.
