Symmetry operations

8 per cell

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 128 atoms drawn above are these sites multiplied by all 8 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

AB11C3D_mC128_15_f_ae10f_3f_f-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mC128, then the space-group number 15, then the Wyckoff letters occupied by each element in turn (O: 4a; O: 4e; Mo: 8f; O: 8f; O: 8f; O: 8f; O: 8f; O: 8f; O: 8f; O: 8f; O: 8f; O: 8f; O: 8f; P: 8f; P: 8f; P: 8f; Si: 8f). Two structures with the same label are the same arrangement with different cell parameters or coordinates.

Note: Monoclinic Model.
