Na4Ge13 is a framework structure with small and large channels that hold Na and is the first known example of a guest−host structure in which discrete (Ge4)4− Zintl polyanions are confined inside the channels of a three-dimensional covalent framework. These features give rise to temperature-dependent disorder, as confirmed by first-principles calculations and physical properties measurements.
