    Description / Table of Contents: On the Periodic Acids HIO4 and H7I3O14: Novel Preparation, Raman Spectra, and StructureHIO4 and H7I3O14 have been prepared from H5IO6 by dehydration with 100 and 97 p.c. H2SO4, respectively. These substances are identical with those obtained from H5IO6 by thermal dehydration. From their Raman spectra it is concluded that the iodine atoms in the compounds are octahedrally coordinated with oxygen atoms. According to this coordination, HIO4 is polymeric. For both compounds structural formulae are suggested.
    Notes: HJO4 und H7J3O14 werden bei der Entwässerung von H5JO6 mit 100- bzw. 97proz. H2SO4 gebildet. Die Substanzen sind identisch mit denen, die durch thermische Entwässerung von H5JO6 erhalten wurden. Aus den Ramanspektren wird gefolgert, daß in beiden Säuren die Jodatome oktaedrisch von Sauerstoff koordiniert sind. Demnach ist HJO4 polymer; Strukturformeln werden vorgeschlagen, in denen die JO6-Oktaeder gemeinsame Kanten besitzen, also die Jodatome durch je zwei Sauerstoffatome verknüpft sind.
