1

Pearson symbol

hP9 — hexagonal / trigonal, primitive lattice, 9 atoms per conventional cell

Symmetry operations

12 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 9 atoms drawn above are these sites multiplied by all 12 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

A2BC6_hP9_189_c_b_fg-002: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hP9, then the space-group number 189, then the Wyckoff letters occupied by each element in turn (Co: 1b; As: 2c; Zr: 3f; Zr: 3g). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
