MCQ
[Pt(NH3​)4​][CuCl4​] and [Cu(NH3​)4​][PtCl4​] are known as:
  • A
    Ionisation isomers
  • B
    Coordination isomers
  • C
    Linkage isomers
  • D
    Polymerisation isomers.

Answer

  1. Coordination isomers

Explanation:

Different complex ions have the same molecular formula. Ligands are interchanged between the complex cation and complex anion. These type of complexes are called coordination isomers.

In [Pt(NH3​)4​][CuCl4​], ammonia ligands are attached to Pt metal and chloride ligands are attached to Cu metal.

In [Cu(NH3​)4​][PtCl4​], ammonia ligands are attached to Cu metal and chloride ligands are attached to Pt metal.
