Cage it: A central PH2− ion (see picture, magenta) is encapsulated within a container of twelve tert-butoxides (red and black) in an icosahedral arrangement. The twelve or thirteen sodium countercations are dynamically disordered over the twenty corners of a regular dodecahedron (blue). The estimated activation barriers for sodium exchange are remarkably low (10–30 kJ mol−1) and in the range of fast Li+ ion conductors.
