Pi Back Bonding

           Pi back bonding also called Pi back donation. In this bond electrons move from an atomic orbital on one atom to Pi * antibonding orbital on another atom or ligand. Mostly common in organo-metallic chemistry of transition metals with multi-atomic ligand such as carbon monoxide , ethylene or the nitrosonium cations. Electrons from the metals are used to bond to the ligand, in the process relieving the excess negative charge.
