Electronic Configuration of the Octahedral Co(II) Complex
The electronic configuration of the octahedral Co(II) complex can be determined using the crystal field theory. In this theory, the ligands surrounding the central metal ion cause a splitting of the d orbitals into two sets of orbitals with different energies:
- t2g orbitals - lower in energy and occupied by 5 electrons
- eg orbitals - higher in energy and occupied by 2 electrons
The electronic configuration of the complex can be represented as:
- t2g5eg2
Magnetic Moment of the Complex
The magnetic moment of the complex can be calculated using the formula:
- μ = √(n(n+2))BM
where n is the number of unpaired electrons and BM is the Bohr magneton. For the given electronic configuration, the number of unpaired electrons is:
- n = 2
Substituting the values in the formula:
- μ = √(2(2+2))BM = 2BM
Therefore, the magnetic moment of the complex is 4.0 BM which is not consistent with the electronic configuration t2g5eg2. This can be explained by invoking the concept of spin-orbit coupling.
Spin-Orbit Coupling
Spin-orbit coupling is the interaction between the magnetic field generated by the motion of electrons (spin) and the magnetic field generated by the motion of electrons around the nucleus (orbit). This interaction causes a splitting of the energy levels of the d orbitals into two sets:
- t2g and eg' - lower in energy
- eg and t2g' - higher in energy
The electronic configuration of the complex can be rewritten as:
- t2g6eg1
This configuration has one unpaired electron in the eg orbital, which gives a magnetic moment of:
- μ = √(1(1+2))BM = 1.73BM
The observed magnetic moment of 4.0 BM can be explained by assuming that the complex is in a high spin state, where the eg and t2g' levels are close in energy and the electron can occupy both orbitals. In this state, the complex has two unpaired electrons in the eg orbital, which gives a magnetic moment of
