Abstract:	The ionic conductivity of the pseudo-2D oxides Li₈MO₆ (M = Zr, Sn), Li₇LO₆ (L = Nb, Ta) and Li₆In₂O₆ has been measured and related to their structures. The ideal lattice consists of octahedral sheets [(Li₂M)O₆]_n, [(Li□L)O₆]_n or [(In₂□)O₆]_n of CdI₂-type, between which 6 Li⁺ ions are inserted with a tetrahedral environment. As expected from the structures the highest lithium mobility is observed for Li₇LO₆ phases and the smallest one for Li₈MO₆.
