Solid-state spectroscopy and crystallography

The vibrational spectra of H 5 IO 6 and a number of periodates containing the anion IO 6 5- are reported and frequencies are assigned. The force constants of the IO 6 5- ion are interpreted on the basis of noticeable π bonding. The IO bonds in H 5 IO 6 are not all equivalent. As shown by their Raman spectra, solutions of H 5 IO 6 in concentrated strong acids contain the hexahydroxoiodine(VII) ion I (OH) 6 + with six equivalent IO bonds.
