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 944 atoms drawn above are these sites multiplied by all 192 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

A7B12C40_cF944_226_abi_j_efgh2ij-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cF944, then the space-group number 226, then the Wyckoff letters occupied by each element in turn (Mo: 8a; Mo: 8b; Mo: 96i; Sn: 192j; Zn: 48e; Zn: 48f; Zn: 64g; Zn: 96h; Zn: 96i; Zn: 96i; Zn: 192j). Two structures with the same label are the same arrangement with different cell parameters or coordinates.

Coordinates and cell from the AFLOW Encyclopedia of Crystallographic Prototypes, entry A7B12C40_cF944_226_abi_j_efgh2ij-001 (M. J. Mehl et al., Comput. Mater. Sci. 136, S1 (2017); D. Hicks et al., ibid. 161, S1 (2019) and 199, 110450 (2021); S. Eckert et al., ibid. 240, 112988 (2024)). Symmetry elements, Wyckoff assignment and the diagram are computed on this page from the group operations.
