Symmetry operations

12 per cell

Crystallographic sites

The multiplicity and the Wyckoff letter say how many copies of the site the group makes in one cell and on which kind of symmetry element the site sits; the 68 atoms drawn above are these sites multiplied by all 12 operations. Press Wyckoff under Colour to see the sites, and tick a symmetry element on the left to see which atoms lie on it.

How to read the label

A27B7_hP68_175_chjk3l_ejk-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hP68, then the space-group number 175, then the Wyckoff letters occupied by each element in turn (Ag: 2c; Gd: 2e; Ag: 4h; Ag: 6j; Gd: 6j; Ag: 6k; Gd: 6k; Ag: 12l; Ag: 12l; Ag: 12l). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
