These compounds and some of their important physical properties are listed in Table 13-9. The preparations of C1F and BrF have already been mentioned. Chlorine trifluoride may be prepared by direct combination of the elements at 200 to 300°C and is available commercially. It is purified by converting it into KC1F4 by the action of KF and thermally decomposing the salt at 130 to 150°C. Chlorine pentafluoride (C1F5) can be made efficiently either by interaction of F2 with C1F3 or by the reaction ... 

The physical properties of chlorine trifluoride are given in Table 7 [75-83],... 

The 1 1 chlorine trifluoride-platinum pentafluoride adduct, m. p. I7l , and the 1 1 iodine pentafluoride adduct, m. p. 140° resemble, in their physical properties, the selenium tetrafluoride adducts of osmium pentafluoride (SeF4,OsFg, m. p. 158°) and iridium pentafluoride (SeF. IrFg, m. p. 133°). They are probably bifluorine-bridged monomers ...
