Crystal asymmetric unit
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. This implies that: mirror planes must form boundary planes of the asymmetric unit; rotation axes must form boundary edges of the asymmetric unit; WebCreate an asymmetric unit object from a list of Elements and an array of fractional coordinates.

Crystal structure is described in terms of the geometry of arrangement of particles in the unit cells. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α, β, γ). The positions … WebWith CrystalMaker you can build any kind of crystal or molecular structure - quickly and easily. Built-in symmetry handling and the elegant spacegroup browser takes the slog out …

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.
