Binary and ternary clathrate phases provide an exciting area of research. Type I clathrates crystallize in the cubic space group Pm-3n and exhibit rich crystal chemistry as well as a wide variety of physical properties. Traditionally Na8Si46 is prepared by the thermal decomposition of the NaSi Zintl salt. A new solid state low temperature synthetic route to prepare NaxSi46, type I clathrate is presented. The characterization by 1H, 23Na and 29Si CP MAS NMR will also be presented.
