crystal system [¦krist·əl ′sis·təm] (crystallography) One of seven categories (cubic, hexagonal, tetragonal, trigonal, orthorhombic, monoclinic, and triclinic) into which a crystal may be classified according to the shape of the unit cell of its Bravais lattice, or according to the dominant symmetry elements of its crystal class.

Likewise, although Crystal Data Determinative Ratios [5] may be used to locate similar lattices within a given crystal system, the normalized reduced cell provides the logical basis for a far more powerful and comprehensive lattice-matching technique which is crystal system independent and conceptually parallel to techniques based on matching reduced cells. The isolates were identified to the species level using the BBL Crystal System (Becton Dickinson, Sparks, MD). In such cases, the compound is often reported in a crystal system of too low symmetry. |
