    Description / Table of Contents: NiH3IO6 · 6 H2O  -  Crystal Structures and Vibrational SpectraThe crystal structure of NiH3IO6 · 6 H2O has been determined by X-ray single-crystal diffraction (Pc, Z = 2, a = 516.74(9), b = 981.5(2), c = 1052.5(2) pm, β = 116.496(8)°) on the basis of 4169 unique reflections (R = 1.96%). The structure is built up of distorted Ni(H2O)62+ and H3IO62- octahedra linked by hydrogen bonding. IR and Raman spectra of both the title compound and isostructural MgH3IO6 · 6 H2O as well as of deuterated specimens are given. There are up to 14 different OH(OD) modes in the spectra of isotopically dilute samples due to the 15 different hydrogen positions of the structure. The internal modes of the meridional H3IO62- ions (pseudo C2v symmetry) are discussed with respect to that double T-shaped entity, which gives rise to only two instead of 3I—O, I—O(H), and OH stretches in the IR and Raman spectra, i.e. the same as for facial (C3v) structured ions.
    Notes: Die Kristallstruktur (Pc, Z = 2) von NiH3IO6 · 6 H2O wurde mittels Röntgen-Einkristallmessungen auf der Basis von 4169 symmetrieunabhängigen Reflexen bestimmt (R = 1,96%). IR- und Raman-Spektren von NiH3IO6 · 6 H2O und der isotypen Verbindung MgH3IO6 · 6 H2O sowie von deuterierten Präparaten werden mitgeteilt. Die Spektren isotypenverdünnter Proben zeigen bis zu 14 OH(OD)-Streckschwingungen entsprechend den 15 verschiedenen Wasserstoff-Positionen der Struktur. Die meridionalen H3IO62--Ionen (Pseudosymmetrie C2v) besitzen wegen der T-förmigen Anordnung der je 3 IO-und IOH-Gruppen nur je 2 IO-, IO(H)- und OH-Streckschwingungen in den IR- und Raman-Spektren und können daher schwingungsspektroskopisch nicht von H3IO62--Ionen mit facialer Struktur (C3v) unterschieden werden.
