Co-ordiantion compounds show structural isomerism and it is different from the nature of the isomerism which we generally come across in organic compounds. The co-ordination and linkage isomers depending upon their upon the number of ions which they furnish upon dissociation in aqueous solution . The isomers belonging to a particular type can also be distinguished from each structural isomerism, the co-ordination compounds are also involved in geometrical and optical isomerism. Whereas optical octahedral and square planar complexes can exhibit geometrical isomerism. One mole of the complex compound `` gives 3 mole of ions on dissolution in water. One mole of the same complex reacts with two moles of `` to yield two moles of . The structure of the complex is :A. `[Co(NH_(3))_(3)Cl_(3)].2NH_(3)`B. `[Co(NH_(3))_(4)Cl_(2).NH_(3)`C. `[Co(NH_(3))_(4)Cl]Cl_(2).NH_(3)`D. `[Co(NH_(3))_(5)Cl]Cl_(2)`
