Q. Describe Linkage Isomerism?

Some ligands can coordinate to the metal through different donor ato...s present in the ligand. They are called ambidentate ligands and they can produce linkage isomer with a metal ion. Isomerism of this kind is shown by the isomeric pair:  [(NH₃) CoNo₂]²⁺ yellow brown known as nitro compound and :  [(NH₃) CoNo₂]²⁺red  coloured isomer known as nitito complex. Other example is: Compounds with ligands like SCN which can bind through S or N donor atom, or sulphoxides, R₂S0, which may combine through S or 0.
