In crystallography, the tetragonal crystal system is one of the 7 crystal systems. 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 and height.

What is body centered tetragonal structure?

The body-centered tetragonal system has the same point group and translational symmetry as the simple tetragonal system, with the addition of a translation to the center of the parallelepiped. Our standard form of the primitive vectors is a1=−a2ˆx+a2ˆy+c2ˆza2= a2ˆx−a2ˆy+c2ˆza3= a2ˆx+a2ˆy−c2ˆz.

Is tetragonal body centered?

There are two tetragonal Bravais lattices: the simple tetragonal (from stretching the simple-cubic lattice) and the centered tetragonal (from stretching either the face-centered or the body-centered cubic lattice).
