The (8-2) structure

The (8-2) structure can be understood as a distorted XY4 structure. The structural data of the (8-2) structure at several radius ratios: $0.261$, $0.264$, $0.267$, $0.270$, $0.273$, $0.275$, and $0.278$, 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.
