SAMLAI

The (22-1) structure can be understood as a clathrate structure. The structural data of the (22-1) structure at several radius ratios: $0.200$, $0.203$, $0.206$, $0.209$, $0.212$, $0.214$, $0.217$, $0.220$, and $0.223$, are downloadable here. The root directory contains several directories, which correspond to the several radius ratios. The structural data files are named by their packing fractions.
