Structure of cuproan adamite, which possesses a tetragonal specialized metric. (a) Original structure. The position at the origin is occupied by Cu and Zn (86 and 14%, respectively); the label of the more abundant atom is shown in the figure. (b) The same structure transformed by applying an m xxz reflection, which is an additional generator of the affine normalizer. If one looks from the negative [001] direction with a 90° counterclockwise orientation one gets (b). Figure drawn with VESTA. |
