The molecule of the title compound, C22H18N4O2S2, lies across a crystallographic inversion centre. The molecule adopts a syn–anti configuration with respect to the positions of the carbonyl groups and terminal phenyl rings relative to the thione S atom across the C—N bond. There are two intramolecular N—H⋯O and C—H⋯S hydrogen bonds within each molecule, resulting in the formation of four six-membered S(6) rings. The central and terminal rings make a dihedral angle of 13.55 (15)°. In the crystal, molecules are linked by intermolecular C—H⋯S hydrogen bonds, forming R
2
2(14) rings and resulting in zigzag chains
