Synthesis and crystal structure of (E)-1,2-bis­[2-(methyl­sulfan­yl)phen­yl]diazene

The title compound, C(14)H(14)N(2)S(2), was obtained by transmetallation of 2,2′-bis­(tri­methyl­stann­yl)azo­benzene with methyl lithium, and subsequent quenching with dimethyl di­sulfide. The asymmetric unit comprises two half-mol­ecules, the other halves being completed by inversion symmetry at the midpoint of the azo group. The two mol­ecules show only slight differences with respect to N=N, S—N and aromatic C=C bonds or angles. Hirshfeld surface analysis reveals that except for one weak H⋯S inter­action, inter­molecular inter­actions are dominated by van der Waals forces only.
