C2/m-32 (host–guest) structure at 150 GPa. 10-coordinate polyhedra (bicapped square antiprisms) are shown: (A) view along the pseudotetragonal axis, (B) side view showing packing of the polyhedra (it can also be seen that the genuine symmetry of this periodic approximant is lower than tetragonal). This structure can be described as self-hosting, the host structure makes a framework in which guest atoms occupy 10-coordinate sites. Other structures are illustrated in SI Text.
