Crystal framework of Bromine

The solid state framework of Bromine is Base centered Orthorhombic.

The crystal structure can be defined in terms of its unit Cell. The unit cells repeats chin in 3 dimensional room to form the structure.

Unit cabinet Parameters

The unit cabinet is represented in terms of its lattice parameters, which are the lengths that the cell edges Lattice Constants (a, b and also c)

a b c
672.65 464.51 870.23 pm

and the angles in between them Lattice angles (alpha, beta and gamma).

alpha beta gamma
π/2 π/2 π/2

The location of the atoms inside the unit cell are explained by the collection of atomic positions ( xi, yi, zi) measured native a recommendation lattice point.

The symmetry nature of the decision are explained by the principle of room groups. All feasible symmetric kinds of corpuscle in three-dimensional space are explained by the 230 an are groups (219 distinct types, or 230 if chiral duplicates are thought about distinct.
