Crystallographic sites
| Site | Element | Wyckoff | Multiplicity | x | y | z |
|---|---|---|---|---|---|---|
| Fe2 | Fe | 2a | 2 | 0.0000 | 0.0000 | 0.0000 |
| B1 | B | 4g | 4 | 0.3940 | 0.8940 | 0.0000 |
| Mo3 | Mo | 4h | 4 | 0.1830 | 0.6830 | 0.5000 |
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 10 atoms drawn above are these sites multiplied by all 16 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
A2BC2_tP10_127_g_a_h-002: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol tP10, then the space-group number 127, then the Wyckoff letters occupied by each element in turn (Fe: 2a; B: 4g; Mo: 4h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
