The vapor pressures of the pentafluorides, ReF/sub 5/, MoF/sub 5/, OsF/ sub 5/, the oxytetrafluorides, ReOF/sub 4/, MoOF/sub 4/, WOF/sub 4/, and the oxyfiuorides ReOF/sub 5/ and ReO/sub 2/F/sub 3/ were measured by a static method using a diaphragm gauge of high sensitivity. The physica- 1 constants, heats of sublimation and vaporization, and entropies of vaporization were derived from the vaporpressure data. The oxypentafiuoride, ReOF/sub 5/ was studied in detail and a hitherto unknown solid-solid transition at 30.0 deg is reported. The thermal disproportionation of the pentafluorides is described.
