4-Amino-1-(2-benzoyl-1-phenyl-eth-yl)-3-phenyl-1H-1,2,4-triazol-5(4H)-thione.

In the title compound, C(23)H(20)N(4)OS, the two phenyl rings of the diphenyl-propanone 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, mol-ecules are paired into centrosymmetric dimers via pairs of inter-molecular N-H⋯O and N-H⋯S hydrogen bonds.
