Coordination Complex

Transition metals are common central central atoms or ions as they have valence shell electrons to accept pair of electrons from ligands
Coordination number refers to total number of sigma bonds by which ligands are attached to coordination centre
The coordination sphere is the non-ionizable part of a complex compound, which consists of a central transition metal ion surrounded by neighbouring atoms or groups enclosed in a square bracket.
The coordination centre, the ligands attached to the coordination centre, and the net charge of the chemical compound as a whole form the coordination sphere when written together.
This coordination sphere is usually accompanied by a counter ion (the ionizable groups that attach to charged coordination complexes).
The geometric shape formed by the attachment of the ligands to the coordination centre is called the coordination polyhedron.
The oxidation number of the central atom can be calculated by finding the charge associated with it when all the electron pairs that are donated by the ligands are removed from it.
