Coordination isomers are coordination salts in which there is an interchange of ligands between the metal in the cation and the metal in the anion.

Examples of pairs of coordination isomers are:

  • Co(NH₃)₆³⁺ Cr(CN)₆³⁻ and Cr(NH₃)₆³⁺ Co(CN)₄³⁻.
  • Zn(NH₃)₄²⁺ CuCl₄²⁻ and Cu(NH₃)₄²⁺ ZnCl₄²⁻
  • Co(NH₃)₆³⁺ Cr(C₂O₄)₃³⁻ and Cr(NH₃)₆³⁺ Co(C₂O₄)₃³⁻
  • Co(NH₃)₆³⁺ Cr(CN)₆³⁻ and Cr(NH₃)₆³⁺ Co(CN)₆³⁻
