Question

The total number of possible isomers of tge complex compound (cu(nh3)4)(ptcl4) is

Answer 1

Hey,

In [Cu(NH3)4][PtCl4] 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.
Hence, 2 isomers are there.
