Crystal structure of Bromine

The solid state structure of Bromine is Base centered Orthorhombic.

The decision structure deserve to be explained in regards to its unit Cell. The unit cells repeats chin in 3 dimensional an are to kind the structure.

Unit cell Parameters

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

a b c
672.65 464.51 870.23 pm

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

alpha beta gamma
π/2 π/2 π/2

The positions of the atoms inside the unit cabinet are explained by the set of atom positions ( xi, yi, zi) measured from a referral lattice point.

The symmetry nature of the crystal are defined by the ide of space groups. All possible symmetric kinds of particles in three-dimensional an are are described by the 230 an are groups (219 distinct types, or 230 if chiral copies are considered distinct.
