In a triclinic crystal
In crystallography, the triclinic (or anorthic) crystal system is one of the 7 crystal systems. A crystal system is described by three basis vectors. In the triclinic system, the crystal is described by vectors of unequal length, as in the orthorhombic system. In addition, the angles between these vectors must all be different … See more The triclinic crystal system class names, examples, Schönflies notation, Hermann-Mauguin notation, point groups, International Tables for Crystallography space group number, orbifold, type, and space groups are … See more • Crystal structure • Crystal system See more • Media related to Triclinic crystal system at Wikimedia Commons See more Web10 Pinacoid. A rhombohedral crystal has six faces, 12 edges, and 8 vertices. Pinacoid: A pinacoid is composed of only two parallel faces. In this case, the top and bottom face are the pinacoid forms (the blue faces). There are a …

WebNov 7, 2024 · Hexagonal: When you look at the crystal on end, the cross-section is a six-sided prism or hexagon. Trigonal: These crystals possess a single 3-fold axis of rotation instead of the 6-fold axis of the hexagonal division. Triclinic: These crystals are not usually symmetrical from one side to the other, which can lead to some fairly strange shapes.

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".
