4-Amino-1-(2-benzoyl-1-phenylethyl)-3-phenyl-1H-1,2,4-triazol-5(4H)-thione

In the title compound, C23H20N4OS, the two phenyl rings of the diphenylpropanone fragment form a dihedral angle of 86.8 (1)°, and the third phenyl ring attached to the triazole ring is twisted from the latter at 40.1 (1)°. In the crystal, molecules are paired into centrosymmetric dimers via pairs of intermolecular N—H...O and N—H...S hydrogen bonds
