Bis(diphenyl-phospho-rothio-yl) tris-ulfide.

In the title compound, C(24)H(20)P(2)S(5), the P atoms are arranged trans with respect to the S(3) group and the S=P-S-S systems have cisoid geometry, with an average S-P-S-S torsion angle of -56.7°. The dihedral angles between the two phenyl rings attached to the P atoms are 87.33 (12) and 75.67 (10)°. In the crystal structure, the mol-ecules are linked into chains running parallel to the a axis by weak inter-molecular C-H⋯S hydrogen bonds. Centrosymmetrically related chains are further connected by π-π stacking inter-actions, with a centroid-to-centroid distance of 3.795 (5) Å.
