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 16 atoms drawn above are these sites multiplied by all 16 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

A4BC3_oI16_71_m_a_bf-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oI16, then the space-group number 71, then the Wyckoff letters occupied by each element in turn (Co: 2a; Sc: 2b; Sc: 4f; C: 8m). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
