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

Abstract

The title 1,2,4-triazole compound, C34H34FN 5S, exists in a trans configuration with respect to the acyclic C=N bond. An intra-molecular 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 diphenyl-amino 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] inter-actions; mol-ecules are stacked along the b axis.
