Crystallographic sites
| Site | Element | Wyckoff | Multiplicity | x | y | z |
|---|---|---|---|---|---|---|
| In1 | In | 1a | 1 | 0.0000 | 0.0000 | 0.0000 |
| Nb2 | Nb | 1b | 1 | 0.0000 | 0.0000 | 0.5000 |
| S3 | S | 2h | 2 | 0.3333 | 0.6667 | 0.3200 |
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 4 atoms drawn above are these sites multiplied by all 12 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
ABC2_hP4_187_a_b_h-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hP4, then the space-group number 187, then the Wyckoff letters occupied by each element in turn (In: 1a; Nb: 1b; S: 2h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
