The title compound, C21H14N4OS, was prepared from the reaction of N-2[2-1H-benzimidazol-2-ylthio)phenyl]-N'benzoylthiourea with dicyclohexylcarbodiimide. A puckered seven-membered ring and a short H ... H contact between two rings cause the whole molecule to be non-coplanar, even though the delocalized pi-bonding system is planar. There is an intramolecular hydrogen bond between the amine H atom and the O atom of the carbonyl group.
