In the case of Ag 6 M 2 TeO 6 , it was observed that the inter-layer distance is relatively substantial, approximately 6 Å, in contrast to Na 2 Ni 2 TeO 6 , which exhibits an inter-layer distance of approximately 3 Å. Consequently, mobile cations within the bilayer have a tendency to approach the oxygen layer, resulting in a splitting of the Ag + conduction layer. However, it is essential to emphasize that a more comprehensive and detailed investigation is needed to gain a thorough understanding of the cationic diffusional pathways and the underlying diffusion mechanisms that govern these intriguing materials.
