Title: Synthesis and Crystal Structure of New Indium Iodate (K{sub 0.6}Na{sub 0.4}Ba)In[IO{sub 3}]{sub 6}

Abstract

Crystals of new indium iodate (K{sub 0.6}Na{sub 0.4}Ba)In[IO{sub 3}]{sub 6} were prepared by the hydrothermal synthesis. The unit-cell parameters are a = 11.3984(3) Å, с = 11.3817(3) Å, sp. gr. R3̅. The chemical formula of the compound was derived from the structure determination and refinement with anisotropic displacement parameters to R = 0.0284. In the structure the InO{sub 6} octahedra share vertices with six umbrella-like [IO{sub 3}]–groups typical of iodates and form isolated 3̅-symmetric charged In[IO{sub 3}]{sub 6}{sup 3−} clusters. Large Ba, K, and Na cations occupy a common site on a threefold axis due to the isomorphous substitution and compensate the charge of the clusters. The new structure extends the family of the recently discovered alkali-metal and barium iodates containing Ti and Zr atoms in octahedral sites. The iodate K{sub 2}Ge[IO{sub 3}]{sub 6} containing Ge atoms in the centers of octahedra is the parent compound of this structural family.
