A unit cell is described by six lattice parameters: edge dimensions ,, and inter-edge angles , , . There are seven possible crystal systems that can produce an infinite lattice in three-dimensional space so that each lattice point has an identical environment.
WebCrystal systems are all the ways that rotational axes of symmetry can be combined and connected to a lattice. There are 7 crystal systems in 3D, which directly connect to 32 point groups when adding mirror planes and inversion. The 7 crystal systems are: Cubic, Hexagonal, Tetragonal, Trigonal, Orthorhombic, Monoclinic, Triclinic.

In crystallography, a crystal system is a set of point groups (a group of geometric symmetries with at least one fixed point). A lattice system is a set of Bravais lattices. Space groups are classified into crystal systems according to their point groups, and into lattice systems according to their Bravais lattices. Crystal systems that have space groups assigned to a common lattice system are co…
WebEach crystal lattice is defined by a crystal system. In three-dimensions, there are seven crystal systems: triclinic, monoclinic, orthorhombic, hexagonal, rhombohedral, tetragonal, and cubic. These collection of systems are called the Bravais lattices. One example of a crystalline material is iron.
