Abstract: In the title compound, C28H23N3O, the 1,2,4-triazole ring deviates slightly from planarity adopting a N3TC2 conformation which is distorted towards an EC2 conformation. The plane around the ethylene unit makes a dihedral angle of 17.32 (11)° with the mean plane [r.m.s. deviation = 0.036 (1) Å] of the 1,2,4-triazole fragment. The dihedral angles between the four phenyl rings and the 1,2,4-triazole ring are 31.01 (10), 49.01 (8), 78.55 (6) and 41.51 (9)°. In the crystal, molecules are linked along [100] by weak C-H...O hydrogen bonds.
