M. Kulcsar, A. Silvestru and M. Vonas

Abstract: In the title compound, C₂₄H₂₀P₂S₅, the P atoms are arranged trans with respect to the S₃ 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 molecules are linked into chains running parallel to the a axis by weak intermolecular C-HS hydrogen bonds. Centrosymmetrically related chains are further connected by - stacking interactions, with a centroid-to-centroid distance of 3.795 (5) Å.
