Crystallographic sites

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 66 atoms drawn above are these sites multiplied by all 36 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

A3B2C14D3_hR22_166_d_ab_c2h_e-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hR22, then the space-group number 166, then the Wyckoff letters occupied by each element in turn (Mn: 3a; Mn: 3b; O: 6c; La: 9d; Sb: 9e; O: 18h; O: 18h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
