In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the …

In crystallography, the tetragonal crystal system is one of the 7 lattice point groups. Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the cube becomes a rectangular prism with a square base (a by a) and height (c, which is different from a).

Cubic is a coordinate term of tetragonal. In context|crystallography|lang=en terms the difference between cubic and tetragonal is that cubic is (crystallography) having three equal axes and all angles 90° while tetragonal is (crystallography) having two equal axes and one unequal, and all angles 90°. As adjectives the difference between cubic and tetragonal
Rutile is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks.. Thermodynamically, rutile is the most stable polymorph of TiO 2 at all temperatures, exhibiting lower total free energy than metastable phases of anatase or brookite. Consequently, the transformation of the metastable TiO 2 polymorphs to rutile is irreversible.

BaTiO3 is (Cubic) Perovskite structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, and faces with eight equivalent TiO6 octahedra.

It is a translucent honey-coloured crystal which can be polished and faceted to form striking gemstones. It crystallizes in the tetragonal system and occurs both in good crystals and as formless masses. It is soft with a Mohs hardness of 2 to 2.5 and has a low specific gravity of 1.6.
The hexagonal crystal family consists of two crystal systems: trigonal and hexagonal.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 (see table in Crystal system#Crystal classes).. The trigonal crystal system consists of the 5 point groups that have a single three-fold rotation axis, which ...
Lead(II,IV) oxide has a tetragonal crystal structure at room temperature, which then transforms to an orthorhombic (Pearson symbol oP28, Space group Pbam, No. 55) form at temperature 170 K (−103 °C). This phase transition only changes the symmetry of the crystal and slightly modifies the interatomic distances and angles.
ZrO2 crystallizes in the tetragonal P4_2/nmc space group. The structure is three-dimensional. Zr4+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.09 Å) and four longer (2.44 Å) Zr–O bond lengths. O2- is bonded to four equivalent Zr4+ atoms to form a mixture of distorted edge and corner-sharing OZr4 tetrahedra.
The Unique Symmetry Element of the Tetragonal Crystal System The single 4-fold axis of rotational symmetry is unique to the tetragonal crystal system. The only other crystal system with a 4-fold axis is the Isometric System, which often has three of them mutually perpendicular to each other.
