Crystal structure of Chlorine
The solid state framework of Chlorine is Base focused Orthorhombic.
The decision structure have the right to be described in regards to its unit Cell. The unit cell repeats itself in 3 dimensional room to type the structure.
Unit cell Parameters
The unit cabinet is represented in terms of its lattice parameters, which are the lengths of the cell edges Lattice Constants (a, b and also c)
| 622.35 | 445.61 | 817.85 pm |
and the angles in between them Lattice angles (alpha, beta and also gamma).
| π/2 | π/2 | π/2 |
The positions of the atoms inside the unit cell are described by the collection of atomic positions ( xi, yi, zi) measured indigenous a reference lattice point.
The symmetry properties of the crystal are described by the concept of space groups. All feasible symmetric arrangements of corpuscle in three-dimensional room are described by the 230 an are groups (219 distinct types, or 230 if chiral duplicates are considered distinct.
