4-Benzyl-1-p-tolyl-1H-1,2,4-triazol-5(4H)-one.

In the title compound, C(16)H(15)N(3)O, the triazole ring makes dihedral angles of 7.08 (2) and 74.53 (3)° with the two outer aromatic rings. The crystal packing is stabilized by very short inter-molecular C-H⋯O hydrogen bonds and weak π-π stacking inter-actions [centroid-to-centroid distance 3.632 (3) Å], resulting in the formation of zigzag chains parallel to the b axis.
