Like zeolites , K 6 Sn[Zn 4 Sn 4 S 17 ] (see structure) has remarkable ion‐exchange properties and forms CsK 5 Sn[Zn 4 Sn 4 S 17 ] and RbK 5 Sn[Zn 4 Sn 4 S 17 ] in the presence of the Cs + and Rb + ions, respectively. These compounds have an open framework comprising [Zn 4 Sn 4 S 17 ] 10− clusters linked by Sn 4+ centers and are remarkably stable. One‐fifth of the K + ions play an important templating role in stabilizing the framework. Zn blue, Sn red, S yellow, K orange.
