P-[N-(Diphenyl-phospho-rothio-yl)iso-propyl-amino]-N-isopropyl-P-phenyl-thio-phosphinic amide.

The title compound, C(24)H(30)N(2)P(2)S(2), was obtained by the reaction of Ph(2)PN(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)°.
