Complex compounds are molecular compounds which retain their identities even when dissolved in water. They do not give all the simple ions in solution but instead furnish complex ions. The complex compounds are often called coordination compounds because certain groups called ligands are attached to the central metal ion by coordinate or dative bonds. coordination compounds exhibit isomerism, both structural and stereoisomerism. the structure, magnetic property, colour and electrical properties of complexes are explained by various theories: Q. The oxidation number, coordination number and magnetic moment in the following complex is: [Cr(C_(2)O_(4))_(2)(NH_(3))_(2)^(-)]
