Concept Introduction:
Naming coordination compounds:
- 1) Name the cation first and then anion.
- 2) When naming the name of the complex ion or molecule, name the ligands first, in alphabetical order, followed by the name of the metal.
- 3) If the coordination complex is an anion, the suffix-ate is added to the metal name.
- 4) Following the name of the metal, the oxidation state of the metal is given in roman numerals.

Concept Introduction:
Coordination compounds: The compounds having coordination covalent bonds which form when metal ions react with polar molecules or anions.
Ligands: The ions or molecules that forms coordination covalent bond with metal ions in a coordination compound. Ligands should have minimum one lone pair of electron, where it donates two electrons to the metal. Metal atom accepts the electron pair from a ligand forming a coordination bond.
The strong-field ligands results in pairing of electrons present in the complex and leads to diamagnetic species , while the low-field ligand do not have tendency to pair up the electrons therefore forms paramagnetic species.
Ligand field theory: It is used to explain the bonding between metal and ligand in a coordination complex. Ligand field theory is explained in terms of electrostatic interaction of between metal ion and ligands.
The five d orbitals get divided into two sets that are
