WebA 'crystal family' is a well defined and unambiguous concept in crystallography [International Tables for Crystallography (1983), sections 2.1 and 8.2.6]. Comparing the classification … Crystals can be classified in three ways: lattice systems, crystal systems and crystal families. The various classifications are often confused: in particular the trigonal crystal system is often confused with the rhombohedral lattice system, and the term "crystal system" is sometimes used to mean "lattice system" or "crystal family".
