Question

$\stackrel{II}{\left[Pt\right(N{H}_3{)}_4]}\stackrel{IV}{\left[PtC{l}_6\right]}$ and $\stackrel{IV}{\left[Pt\right(N{H}_3{)}_{4}C{l}_2]}\stackrel{II}{\left[PtC{l}_4\right]}$ complexes represent the example of

• A. ligand isomerism
• B. hydrate isomerism
• C. linkage isomerism
• D. co-ordination isomerism

Answer 1

The correct option is D co-ordination isomerism

Coordination isomerism is a form of structural isomerism in which the composition of the complex ion varies. In a coordination isomer the total ratio of ligand to metal remains the same, but the ligands attached to a specific metal ion change.
Hence, this is an example of co-ordination isomerism.
