COMPLEX COMPOUNDS

The complex compounds are the compound which consist of two or more ligands around the central atom by coordinate bond. central metal atom is the metallic ion which is capable of coordinating with ligands and form complex compound.the central metal atom must have the empty orbital in its electronic configuration, this empty orbital provide a room to accommodate lone pair supplied by ligands. On the other hand, ligand are molecules  or ions which can coordinate with the central atom to form complex compound. characteristically, ligands must have atom possessing lone pair(s) in their electronic structure. these lone pairs are used in dative or coordinate bond formation between the central metal  and ligands.
