Crystal framework of Cobalt
The solid state framework of Cobalt is Simple Hexagonal.
The decision structure deserve to be described in regards to its unit Cell. The unit cells repeats chin in three dimensional an are to type the structure.
Unit cell Parameters
The unit cabinet is represented in regards to its lattice parameters, which space the lengths the the cell edges Lattice Constants (a, b and also c)
| 250.71 | 250.71 | 406.95 pm |
and the angles in between them Lattice angles (alpha, beta and gamma).
| π/2 | π/2 | 2 π/3 |
The positions of the atoms inside the unit cabinet are defined by the collection of atomic positions ( xi, yi, zi) measured native a reference lattice point.
The symmetry properties of the decision are defined by the concept of room groups. All possible symmetric arrangements of particles in three-dimensional an are are described by the 230 an are groups (219 distinct types, or 230 if chiral duplicates are thought about distinct.
