The (12-6) structure

The (12-6) structure is a distorted AlB2 structure. The structural data of the (12-6) structure at several radius ratios: $0.537$, $0.540$, $0.543$, $0.546$, $0.549$, $0.552$, $0.554$, $0.547$, $0.560$, $0.563$, $0.566$, $0.569$, $0.572$, $0.574$, $0.577$, and $0.580$, 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.
