oP176 — orthorhombic, primitive lattice, 176 atoms per conventional cell

Symmetry operations

4 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 176 atoms drawn above are these sites multiplied by all 4 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

A3BCD14E3_oP176_19_6a_2a_2a_28a_6a-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oP176, then the space-group number 19, then the Wyckoff letters occupied by each element in turn (Al: 4a; Al: 4a; Al: 4a; Al: 4a; Al: 4a; Al: 4a; C: 4a; C: 4a; N: 4a; N: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; O: 4a; P: 4a; P: 4a; P: 4a; P: 4a; P: 4a; P: 4a). Two structures with the same label are the same arrangement with different cell parameters or coordinates.

Note: AlPO₄-53(A).
