WebJul 26, 2014 · Seven Major Crystal Systems • Isometric • Tetragonal • Orthorhombic • Monoclinic • Triclinic • Trigonal • Hexagonal There are actually 32 classes of symmetry, 230 space groups that are observable through x-ray analysis, but for most secondary school settings I discuss only 6 major classes,. I have not discussed trigonal separately. 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).
