Definition:
Symmetry-equivalent position in the 'xyz' representation. Except for the space group P1, these data will be repeated in a loop. The format of the data item is as per International Tables for Crystallography Vol. A. (2002). All equivalent positions should be entered, including those for lattice centring and a centre of symmetry, if present. In order for the defaults to work correctly, the identity operation should have _space_group_symop_id or _symmetry_equiv_pos_site_id set to 1, and _space_group_symop_operation_xyz or _symmetry_equiv_pos_as_xyz set to x,y,z; i.e. the operation labelled 1 should be the identity operation.Example:
-y+x,-y,1/3+z |
