(E)-1-[2-(Methyl­sulfan­yl)phen­yl]-2-({(E)-2-[2-(methyl­sulfan­yl)phen­yl]hydrazinyl­idene}(nitro)­meth­yl)diazene

In the title compound, C₁₅H₁₅N₅O₂S₂, the phenyl rings make dihedral angles of 4.03 (4) and 9.77 (5)° with the plane defined by the central N—N—C—N—N atoms (r.m.s. deviation = 0.010 Å). The C—S—C—C torsion angles of the methyl­sulfanyl groups with their respective phenyl rings are −7.47 (13) and −72.07 (13)°. The shortest centroid–centroid distance of 3.707 Å occurs between the two π-systems N—N—C—N—N and the benzene ring in the diazene 1-position. The H atom bound to the N atom is involved in intra­molecular N—H...N and N—H...S contacts, while the nitro O atoms are involved in inter­molecular C—H...O contacts.
