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 54 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

A6B14C7_mP54_4_6a_14a_7a-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mP54, then the space-group number 4, then the Wyckoff letters occupied by each element in turn (C: 2a; C: 2a; C: 2a; C: 2a; C: 2a; C: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; H: 2a; O: 2a; O: 2a; O: 2a; O: 2a; O: 2a; O: 2a; O: 2a). Two structures with the same label are the same arrangement with different cell parameters or coordinates.

Note: α-D-glucose monohydrate.
