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.
