Chemistry - Coordination Chemistry Question with Solution | TestHub

The given complex is $[Pt(N{H}_3{)}_4][Pd(C_2{O}_4{)}_2]$.

Coordination isomerism involves the exchange of ligands between the cationic and anionic coordination spheres.

For the coordination isomer, the ligands are exchanged: $[Pd(N{H}_3{)}_4][Pt(C_2{O}_4{)}_2]$.

Cationic part: $[Pd(N{H}_3{)}_4{]}^{2+}$ (Tetraamminepalladium(II))

Anionic part: $[Pt(C_2{O}_4{)}_2{]}^{2-}$ (Bis(oxalato)platinate(II))

Thus, the IUPAC name is Tetraamminepalladium(II) bis(oxalato)platinate(II).
