Crystal Structure of Lithium Iodate
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+/-0.003A, c=5.155A+/-0.005A. The space group assigned is D66 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 (uu0) (0u¯0) (u¯00) (u¯u¯12) (0u12) (u012) with u=13. 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.
