P4O6Se has been synthesized by photochemical reaction between P4O6 and elemental selenium in CS2 in presence of iodine as a catalyst. Single crystals form at purification via sublimation. The compound (m.p. 46°C) crystallizes in the monoclinic space group P21/C (no. 14) with a=1051.8(2), b=652.9(1), c=1178.6(2) pm, β=109,29(1)°, Z=4. Within the limits of experimental error, the molecules exhibit C3v symmetry. IR, Raman, and (31)P n.m.r. (solution) spectra of the compound are reported and discussed. The geometry of the molecule as determined by theoretical methods (SCF level) is in good agreement with the experimental results.

P4O7S was synthesized for the first time and characterized by X-ray structure determination (single-crystal methods) and (31)P n.m.r. (solution and MAS-solid) (P1-, a=687.2(1); b=718.2(2); c=809.1(1) pm; α=92.58(1)°; β=104.43(1)°; γ=94.82(2)°; 2907 difractometer data; R1=0.030; wR**2=0.102). The different influences of terminally bound oxygen and sulfur on the geometry of the P4O6 cage are discussed.

The P4/O3 matrix system has been reinvestigated by using dilute P4 and a wide range of photolysis wavelengths. With red photolysis the major product is terminal P4O; with ultraviolet photolysis absorptions for oxo-bridged tetrahedral P4O and cyclic planar P4O plus a series of oxo-bridged absorptions leading to P4O6 and P4O7 dominate. Vacuum ultraviolet photolysis and glow discharge of P4O6 produced an absorption for P4O7 and three absorptions common to the P4/O3 photolysis system, which are assigned to oxo-bridged P4O5, P4O4, and P4O3.

P4O6 was reacted with oxygen atoms (16O and 18O) obtained from ozone photolysis and discharge of oxygen.The P4O7-10 and P4O6(18)O1-4 products were trapped in solid argon and examined by infrared spectroscopy.The spectra of the four higher oxides support a central P4O6 cage structure with additional terminal P=16O or P=18O bonds.The P=16O and P=18O vibrations are identified in four higher oxides, and assignments are proposed for several of the more intense P4O6 cage absorptions.
