Concept Introduction:
Coordination compounds: The compounds having coordination covalent bonds which form when metal ions react with polar molecules or anions.
Crystal field theory: Bonding in coordination compounds accounts for the magnetic property and color of the complex ion. Crystal field theory is explained in terms of electrostatic interaction of between metal ion and ligands.
Crystal field splitting: The energy gap between the splitting of d-orbitals of the metal ion in presence of ligands is known as the crystal field splitting
Paramagnetic property: The presence of unpaired electrons in the electronic configuration of the metal ion in coordination complex.
