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 32 atoms drawn above are these sites multiplied by all 8 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

A3B_oP32_62_ab4c_2c-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oP32, then the space-group number 62, then the Wyckoff letters occupied by each element in turn (O: 4a; O: 4b; O: 4c; O: 4c; O: 4c; O: 4c; W: 4c; W: 4c). Two structures with the same label are the same arrangement with different cell parameters or coordinates.

Note: Original \beta-WO₃ (Obsolete).
