Platinum group metals pentafluorides

Although single crystals of IrFs have been obtained, none were of suitable size and shape to yieid an accurate structure and when it became clear that the structure would be no more precise than that reported for RuFs, the analysis was abandoned. Nevertheless, the precession and Weissenberg photographic data have established the space group P2ila and indicate a close structural relationship to the other platinum-metal pentafluorides. We, therefore, believe that these pentafluorides will all show essentially the same tetrameric unit as detailed for RhFs tB Figures 1 and 2 and Table III.
