WebNov 17, 2024 · Structures determined by X-ray crystallography are typically deposited as files containing the coordinates for one asymmetric unit (ASU). Knowledge of the symmetry operators that describe how the ASUs are arranged relative to each other allows the arrangement of the crystal lattice to be recreated. WebAn asymmetric unit of a space group is a simply connected smallest closed part of space from which, by application of all symmetry operations of the space group, the whole space is filled.
