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 48 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

A2B_tP48_130_2g_g-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol tP48, then the space-group number 130, then the Wyckoff letters occupied by each element in turn (O: 16g; O: 16g; V: 16g). Two structures with the same label are the same arrangement with different cell parameters or coordinates.

Note: Metastable at RT.
