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 14 atoms drawn above are these sites multiplied by all 2 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
AB12C_aP14_2_b_6i_c-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol aP14, then the space-group number 2, then the Wyckoff letters occupied by each element in turn (Cu: 1b; Zr: 1c; F: 2i; F: 2i; F: 2i; F: 2i; F: 2i; F: 2i). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
Note: \gamma-CuZrF₆.
