Abstract

Solid solutions of NH(4)(+) in Cs(2)WS(4) and Rb(2)WS(4) are obtained by precipitation/crystallization from aqueous solutions. By means of (14)N, (87)Rb, and (133)Cs magic angle spinning NMR, compositions and extraordinarily accurate NH(4)(+)-site preferences are established for these materials.
