Complex compounds are molecular compounds which retain their indentities 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 struculre, magnetic property, colour and electrical properties of complexes are explained by various theories. The oxidation number, coordination number and magnetic moment in the following complex Na_(3)[Cr(CN)_(6)] is :

Valence bond theory successfully explains the magnetic behaviour of complexes. The substances which contains unpaired electrons are paramagnetic and paramagnetic character increases as the number of unpaired electrons increases. Magnetic moment of a complex can be determined experimentally and by using formula sqrt(n(n+2)) and we can determine the number of unpaired electrons in it. This information is important in writing electronic structure of complex which in turn also useful in deciding the geometry of complex. Which of the following are diamagnetic ? 1) K_(4)[Fe(CN)_(6)] 2) K_(3)[Cr(CN)_(6)] 3) K_(3)[Co(CN)_(6)] 4) K_(2)[Ni(CN)_(4)]
