Number of isomers of [Pt(NH3)4][CuCl4] complex
In [Pt(NH3)4][CuCl4] complex , both anion and cation can be metal complex ions which yields an isomer and this type of isomerism is referred to as coordination isomerism.
[Pt(NH3)4][CuCl4] and [Cu(NH3)4][PtCl4]
In the first complex, NH3 ligands are associated with Pt and Cl- ligands are associated with Cu whereas it is the reverse in the case of the second complex.[Pt(NH3)4][CuCl4] and [Cu(NH3)4][PtCl4]
Hence, 2 isomers are there.
