What are complex compounds? Give one example?

These are addition compound which retain their identity in the solid as well as in the solution forms. In these compound the individual properties of constituents are generally lost. A complex ferro- cyanide [Fe(CN)₆]^4- ion is formed when aqueous solution of Fe(CN)₂ and KCN are mixed together. The salts of these complex ion are known as complex compounds or coordination compounds.
