The (10-1) structure can be understood as a clathrate structure. The structural data of the (10-1) structure at several radius ratios: $0.225$, $0.228$, $0.230$, $0.233$, $0.236$, $0.239$, $0.242$, $0.245$, $0.247$, $0.250$, $0.253$, $0.256$,
$0.258$, $0.261$, $0.264$, $0.267$, and $0.270$, are downloadable
