Abstract
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 tetrahydrofuran. In the solid state, intramolecular N-H center dot center dot center dot S hydrogen bonding influences the molecular conformation; a P-N-P-N torsion angle of 2.28 (9)degrees is observed. The two phenyl rings attached to one P atom form a dihedral angle of 74.02 (4)degrees.
