Crystallographic sites
| Site | Element | Wyckoff | Multiplicity | x | y | z |
|---|---|---|---|---|---|---|
| Pt3 | Pt | 4a | 4 | 0.0000 | 0.0000 | 0.0000 |
| K2 | K | 8c | 8 | 0.2500 | 0.2500 | 0.2500 |

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 36 atoms drawn above are these sites multiplied by all 192 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
A6B2C_cF36_225_e_c_a-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cF36, then the space-group number 225, then the Wyckoff letters occupied by each element in turn (Pt: 4a; K: 8c; Cl: 24e). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
