The X-ray powder diffraction pattern for tetraphenyldiphosphine dioxide Ph2P(O)P(O)Ph2 can be satisfactorily indexed on the assumption that the compound is isomorphous with tetraphenyldiphosphine disulphide.Calculated crystal data for the dioxide are: monoclinic, P21/c, a = 9.44(1), b = 15.62(3), c = 13.87(3) Angstroem, β = 98.0(1)0 Z = 4.The P-P stretch is assigned in the Raman spectrum of the disulphide at 536 cm-1 and in dioxide at the usually high frequency of 601 cm-1.The reaction of tetraphenyldiphosphine with KSeCN in acetonitrile leads to oxidation of the phosphorous and selenium insertion into the P-P bond, yielding Ph2P(Se)SeP(Se)Ph2, diphenylphosphinodiselenoic anhydroselenide, previously only identified in solution.
