What are linkage isomers? Give me an example

Answer 1

Linkage isomers are coordination compounds that have the same composition but differ in the connectivity of the ligand to the metal.

For example, a thiocyanato group could be connected to the metal atom by either the S atom or the N atom.

Typical ligands that give rise to linkage isomers are:

  • thiocyanate, SCN⁻ and isothiocyanate, NCS⁻
  • selenocyanate, SeCN⁻ and isoselenocyanate, NCSe⁻
  • nitrite, NO₂⁻
  • sulfite, SO₃²⁻

    Two examples of linkage isomers are

    • the violet thiocyanato-κ-S and orange thiocyanato-κ-N isomers
      [(NH₃)₅Co-SCN]²⁺ and [(NH₃)₅Co-NCS]²⁺

    • the yellow nitrito-κ-N and red nitrito-κ-O isomers [(NH₃)₅Co-NO₂]²⁺ and [(NH₃)₅Co-ONO]²⁺

Answer 2

Linkage isomers are coordination compounds that have the same composition but differ in the connectivity of the ligands to the central metal ion. An example is the cobalt(III) hexamine complex, which can exist in two linkage isomeric forms: cis- and trans-. In the cis-isomer, two ammonia ligands are adjacent to each other, while in the trans-isomer, the ammonia ligands are opposite each other.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
