Synthesis and properties of alkali-metal lithium periodatoferrate(III) and periodatocobaltate(III) complexes

Abstract

The pale-yellow LiMFeIO₆ (M=K, Rb or Cs) have been prepared by reaction of MIO₄ , Li⁺ and [Fe(H₂O)₆ ]³⁺ in hot aqueous solution at pH 9. Olive-green LiMCoIO₆ were prepared from MIO₄ , Li⁺ and [Co(H₂O)₆ ]²⁺ in hot alkaline solution using ozonised oxygen as oxidant. These insoluble powders have been characterised by analysis, IR and Raman, UV–VIS and EPR spectroscopy and magnetic measurements. PXRD studies revealed that they are amorphous, but structural data have been obtained via Fe or Co and I K-edge EXAFS, and are consistent with a layered periodate structure type similar to that found previously in MM′IO₆ (M′=Mn, Ni, Ge, etc). ⁵⁷Fe Mössbauer data are reported for LiKFeIO₆ .
