Which magnetic moment calculation can be used to determine the magnetic moment of [co(ox)3]2-?
Accepted Answer
The magnetic moment of [Co(ox)3]2- can be determined using the spin-only formula: μ = √n(n+2) BM, where n is the number of unpaired electrons. To apply this formula, you need to determine the electronic configuration of the cobalt ion in the complex. Since oxalate (ox) is a weak field ligand, it will not cause significant pairing of electrons. Therefore, Co(III) in [Co(ox)3]2- will have a d6 configuration with no unpaired electrons, resulting in a magnetic moment of 0 BM.
