|---|---|---|---|---|---|---|
| P4 | P | 2a | 2 | 0.2500 | 0.7500 | 0.0000 |
| Mo1 | Mo | 2c | 2 | 0.2500 | 0.2500 | 0.6975 |

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 14 atoms drawn above are these sites multiplied by all 8 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
AB5C_tP14_85_c_cg_a-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol tP14, then the space-group number 85, then the Wyckoff letters occupied by each element in turn (P: 2a; Mo: 2c; O: 2c; O: 8g). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
