Abstract: | On Copper‐tetrahydrogen‐decaoxo‐diperiodate‐hexahydrate CuH4I2O10·6H2O: Crystal Structure, Vibrational Spectroscopy and Thermal Analysis By crystallization from a strongly acidic aqueous solution copper‐tetrahydrogen‐decaoxodiperiodate‐hexahydrate CuH4I2O10· 6H2O has been obtained. In the structure of this compound (S.G. P 21/c, Nr.14), Z = 2, a = 1060.2(2) pm, b = 551.1(1) pm, c = 1164.7(2) pm, β = 111, 49(3)°) centrosymmetric [H4I2O10]2— anions in the form of two edge sharing octahedra form layers via hydrogen bonds originating from the acidic, trans‐configurated OH groups of the anions. Raman spectra are given and analyzed with respect to the internal vibrations of the periodate anion. The dehydration of the compound takes place via CuH4I2O10·3H2O and Cu(H2IO5)2 which decomposes at 170 °C to Cu(IO3)2. |
