1.3: The symmetry of crystals - Chemistry LibreTexts

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… WebUsing these elements of symmetry, crystallographers have recognized 32 crystal classes and seven crystal systems.
