Halogen oxide fluorides and related compounds

Periodates form numerous complexes with transition metals in which the octahedral unit acts as a bidentate chelate. Examples are  

This section considers compounds in which X (Cl, Br or I) is bonded to both O and F, i.e. F XOm. Oxofluorides -OF and peroxofluorides -OOF have already been discussed (p. 638) and halogen derivatives of oxoacids, containing -OX bonds are treated in the following section (p. 883). 

Of the 6 possible oxide fluorides of Cl, 5 have been characterized they range in stability from the thermally unstable FCl 0 to the chemically rather inert perchloryl fluoride FCl 03. The others are FC1 02, F3C1 0 and F3C1 02- 

The Halogens Fluorine, Chlorine, Bromine, Iodine and Astatine 

The structures of the chlorine oxide fluorides are summarized in Fig. 17.26, together with those of related cationic and anionic species formed from the neutral molecules by gain or loss or F . The first conclusive evidence for free FCIO in the gas phase came in 1972 during a study of the hydrolysis of CIF3 with substoichiometric amounts of H2O in a flow reactor
