The compound NH(PF2)(PF4) has been prepared from PF2[NH(SiH3)] by reaction with PF5. Vibrational, photoelectron, n.m.r., and mass spectroscopic data have been recorded, and interpreted in terms of the probable structure and conformation of the molecule. At low temperatures the phosphorus(V) group has chemically equivalent equatorial fluorine atoms but non-equivalent axial atoms, indicating restricted
Chloro(trifluorophosphane)gold(I): [Au(PF3)Cl] X-ray quality crystals of [Au(PF3)Cl] (orthorhombic, Pnma) are obtained from a toluene / pentane solution at 6 °C. According to the result of the X-ray structural analysis, [Au(PF3)Cl] contains an almost linear F3P-Au-Cl unit. The shortest Au-Au contacts between two of these units are 3.3495(9) A.
Abstract : The reactions of peroxydisulfuryldifluoride with several substances have been examined. Three new fluorosulfonates, octafluorobis(fluorosulfonato) cyclopentane (C5F8(SO3F)2), tetrafluorobis(fluorosulfonato)ethane (C2F4(SO3F)2) , and tetrafluorobis(fluorosulfonato)sulfur (VI) (SF4(SO3F)2) were produced by direct combination of peroxydisulfuryldifluoride with perfluorocyclopentene (C5F8)

The reactions between CrO2Cl2 and a series of substitutedphosphines have been investigated using matrix isolation infrared spectroscopy. For all of the phosphines except PF3, twin jet co-deposition of the two reagents into argon matrices at 14 K initially led to the formation of weak bands due to the corresponding phosphine oxide. For all of the phosphines, subsequent irradiation with light of lambda

The reaction of SiP/sub 2/O/sub 7/ with rare-earth fluorides and oxides and with UO/sub2/ proceeds at high temperatures (1000/sup 0/ to 1200/sup 0/C) to convert the rare-earth and uranium compounds to ortho- or pyro-phosphates. In these reactions between intimately mixed powders, very finely segregated SiO/sub2/ is formed and distributed throughout the phosphates. This procedure may be useful for
