Abstract
The structure of lithium iodate was determined by using the oscillation and powder methods. Lithium iodate is hexagonal with 2 molecules per unit cell of $a=5.469\ifmmode\pm\else\textpm\fi{}0.003\mathrm{A}$, $c=5.155\mathrm{A}\ifmmode\pm\else\textpm\fi{}0.005\mathrm{A}$. The space group assigned is ${{D}_{6}}^{6}$ and the atom positions are: 2Li in (001/4) (003/4), 2I in (1/3 2/3 1/4) (2/3 1/3 3/4) and 6 O in $(\mathrm{uu}0) (0\overline{u}0) (\overline{u}00) (\overline{u}\overline{u}\frac{1}{2}) (0u\frac{1}{2}) (u0\frac{1}{2})$ with $u=\frac{1}{3}$. The structure is based on hexagonal closest packing, with the lithium and iodine atoms both lying within oxygen octahedra. The atomic distances are Li---O and I---O = 2.23A with lithium octahedra sharing faces with each other, one lithium and one iodine octahedra sharing only edges and two iodine octahedra only corners.
