The title compound, C24H30N2P2S2, was obtained by the reaction of Ph2PN(iPr)P(Ph)N(iPr)H with elemental sulfur in tetra-hydro-furan. In the solid state, intra-molecular N - H⋯S hydrogen bonding influences the mol-ecular conformation; a P - N - P - N torsion angle of 2.28 (9)° is observed. The two phenyl rings attached to one P atom form a dihedral angle of 74.02 (4)°.
