Question

For the coordination complex ion [Co(NH₃)₆]³⁺:

State the magnetic nature of the complex.

For the coordination complex ion [Co(NH₃)₆]³⁺:

State the magnetic behaviour of the complex ion.

Answer 1

[CO(NH₃)₆]³⁺ is diamagnetic. This is because all of the electrons in the d-orbitals of the central Co³⁺ ion are paired, resulting in no unpaired electrons.
