In coordination chemistry, a ligand (/lÉªÉ¡Énd/) is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex.The bonding between metal and ligand generally involves formal donation of one or more of the ligand's electron pairs.or example, an imido ligand in the ionic form has three lone pairs. One lone pair is used as a sigma X donor, the other two lone pairs are available as L type pi donors. If both lone pairs are used in pi bonds then the M-N-R geometry is linear.
