(E)-1-[(Diphenyl­amino)meth­yl]-4-(4-fluoro­benzyl­ideneamino)-3-[1-(4-iso­butyl­phen­yl)eth­yl]-1H-1,2,4-triazole-5(4H)-thione

The title 1,2,4-triazole compound, C(34)H(34)FN(5)S, exists in a trans configuration with respect to the acyclic C=N bond. An intra­molecular C—H⋯S contact generates a six-membered ring, producing an S(6) ring motif. The essentially planar 1,2,4-triazole ring [maximum deviation 0.008 (1) Å] is inclined at 21.43 (5) and 83.03 (6)°, respectively, with respect to the flurophenyl unit and the isobutyl-substituted benzene ring. The diphenyl­amino unit is not planar, as indicated by the dihedral angle between two phenyl rings of 76.95 (6)°. The crystal structure is stabilized by C—H⋯π and π–π [centroid–centroid distance = 3.6169 (6) Å] inter­actions; mol­ecules are stacked along the b axis.
