Crystallographic axis
WebCrystal 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 … WebThe three axes of four-fold symmetry are chosen as the crystallographic axes. (b) Planes of Symmetry: 9 in all. 3 planes of symmetry are at right angles to each other and are termed the principal (axial) planes; 6 planes of symmetry are diagonal in position and bisect the angles between the principal planes. (c) It has a Centre of symmetry. Forms:
