In crystallography, the orthorhombic crystal system is one of the 7 crystal systems.Orthorhombic lattices result from stretching a cubic lattice along two of its orthogonal pairs by two different factors, resulting in a rectangular prism with a rectangular base (a by b) and height (c), such that a, b, and c are distinct.
Crystal systems that have space groups assigned to a common lattice system are combined into a crystal family. The seven crystal systems are triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic. Informally, two crystals are in the same crystal system if they have similar symmetries (though there are many exceptions).
A crystal system is a set of point groups in which the point groups themselves and their corresponding space groups are assigned to a lattice system. Of the 32 point groups that exist in three dimensions, most are assigned to only one lattice system, in which case the crystal system and lattice system both have the same name.
Here {,,,,,} is the lattice system, and {,,,} is the centering type. [2] In Fedorov symbol, the type of space group is denoted as s (symmorphic), h (hemisymmorphic), or a (asymmorphic). The number is related to the order in which Fedorov derived space groups.

In crystallography, the monoclinic crystal system is one of the seven crystal systems. A crystal system is described by three vectors. In the monoclinic system, the crystal is described by vectors of unequal lengths, as in the orthorhombic system. They form a parallelogram prism. Hence two pairs of vectors are perpendicular (meet at right ...

Pinalite is a rare lead tungstate–chloride mineral with formula: Pb 3 WO 5 Cl 2.. Pinalite crystallizes in the orthorhombic crystal system. [5] The orthorhombic system is described as having three crystallographic axes of unequal lengths, normally referred to as c (the longest axis), b (the second longest axis), and a (the smallest axis).
