    P-[N-(Diphenyl-phospho-rothio-yl)iso-propyl-amino]-N-isopropyl-P-phenyl- thio-phosphinic amide
    (Chester : International Union of Crystallography, 2009) Peulecke, N.; Aluri, B.R.; Wöhl, A.; Spannenberg, A.; Al-Hazmi, M.H.
    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)°.

    1,1,2,2-Tetra-phenyl-15-diphosphane 1-sulfide
    (Chester : International Union of Crystallography, 2009) Aluri, B.R.; Peitz, S.; Wöhl, A.; Peulecke, N.; Müller, B.H.; Spannenberg, A.; Rosenthal, U.
    In the title mol-ecule, C24H20P2S, the P - P bond length is 2.2263 (5) Å. The two phenyl rings attached to the three- and five-coordinated P atoms, respectively, form dihedral angles of 56.22 (5) and 71.74 (5)°.
