3-({4-[(2-Methyl­benzyl­idene)amino]-5-sulfanyl­idene-1H-1,2,4-triazol-3-yl}meth­yl)-1,3-benzoxazol-2(3H)-one

In the title compound, C(18)H(15)N(5)O(2)S, a weak intra­molecular C—H⋯S hydrogen bond results in a small dihedral angle of 3.71 (9)° between the methyl­phenyl and triazole rings, which, in turn, form dihedral angles of 80.09 (8) and 77.32 (8)°, respectively, with the benzoxazolone mean plane. In the crystal, N—H⋯O hydrogen bonds link mol­ecules into chains along [001], and weak C—H⋯N hydrogen bonds and π–π inter­actions between the five- and six-membered rings [centroid–centroid distances = 3.5074 (11) and 3.616 (1) Å] consolidate the crystal packing.
