Crystallographic sites
| Site | Element | Wyckoff | Multiplicity | x | y | z |
|---|---|---|---|---|---|---|
| Mn1 | Mn | 1a | 1 | 0.0000 | 0.0000 | 0.0000 |
| Pb3 | Pb | 1d | 1 | 0.3333 | 0.6667 | 0.5000 |
| Te4 | Te | 1e | 1 | 0.6667 | 0.3333 | 0.0000 |

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 9 atoms drawn above are these sites multiplied by all 6 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
AB6CD_hP9_149_a_l_d_e-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hP9, then the space-group number 149, then the Wyckoff letters occupied by each element in turn (Mn: 1a; Pb: 1d; Te: 1e; O: 6l). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
