Crystal asymmetric unit

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 … 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;

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 … Web_____volume of your unit cell_____ the molecular weight of your macromolecule * Z * X Where Z is the number of asymmetric units in the unit cell (i.e. the number of symmetry operators in your space group).
