Crystal 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 … Webadvances in experimental polymorph searching and crystal en-gineering highlight the rich variety of multi-component crys-tals (co-crystals, salts, solvates, etc) as well as crystal structures with multiple molecules in the asymmetric unit. For instance, many well-studied molecules, including aspirin [23], resorcinol
