Abstract

23Na double rotation NMR (DOR) and 81Br magic angle spinning (MAS) are used to investigate the synthesis and assembly of sodium, silver-bromide clusters encapsulated in the porous framework of sodalite. The NMR spectra provide site-specific information on the nano-environments of the charge balancing, extraframework Na+ cations, and the encapsulated Br− anions. The results indicate the possibility of a percolation threshold beyond certain Na+ and Br− loadings.
