dc.description.abstract | Two new quaternary zirconium iodates, BaZr(IO3)(6) and K2Zr(IO3)(6), have been synthesized through hydrothermal reactions using BaCO3 (or K2CO3), ZrO2, and HIO3 as reagents. Single crystal and powder X-ray diffraction were used to determine crystal structures of the compounds. BaZr(IO3)(6) exhibits infinite bands that are composed of ZrO7 pentagonal bipyramids and IO3 trigonal pyramids, in which Ba2+ cations are sandwiched by the bands. K2Zr(IO3)(6) exhibits a molecular structure that is composed of ZrO6 octahedra and IO3 groups. The dimensionality variations seem to be attributable to the flexible coordination numbers of Zr4+ cations with large ionic radii as well as the number of counter cations. Both of the materials are thermally stable up to approximately 440-450 degrees C and decompose to the corresponding metal zirconium oxides above these temperatures. The band gaps for BaZr(IO3)(6) and K2Zr(IO3)(6) are calculated to be 3.1 and 3.0 eV, respectively, using the (K/S)-versus-E plots obtained from the UV-vis diffuse reflectance spectra. Infrared spectra and local dipole moment calculations are also presented. | - |
