| Pd3 | Pd | 1b | 1 | 0.0000 | 0.5000 | 0.0000 |
| Pd4 | Pd | 1c | 1 | 0.0000 | 0.0000 | 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 6 atoms drawn above are these sites multiplied by all 4 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
A2B_mP6_10_mn_bc-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mP6, then the space-group number 10, then the Wyckoff letters occupied by each element in turn (Pd: 1b; Pd: 1c; Cl: 2m; Cl: 2n). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
Note: \delta-Pd₂Cl.
