Ligand
What is Ligand?
A ligand is an ion or molecule that donates a lone pair of electrons to a central metal atom or ion to form a coordinate (dative) bond in a coordination compound. Ligands can be monodentate (donating one lone pair, e.g. NH₃, Cl⁻), bidentate (donating two, e.g. ethylenediamine), or polydentate (chelating). The nature and number of ligands determine the geometry and properties of the complex.
