High- and Low-Spin Octahedral Complexes
How many unpaired electrons are there in the complex ion [CoF_6]^{3-}?
| Determining the Number of Unpaired Electrons in Octahedral Complexes | ||
| Begin by determining the charge and number of d electrons on the metal. | SOLUTION
The metal is Co^{3+} and has a d^{6} electronic configuration. |
|
| Look at the spectrochemical series to determine whether the ligand is a strong-field or a weak-field ligand. | F^{-} is a weak-field ligand, so Δ is relatively small. | |
| Decide if the complex is high- or low-spin and draw the electron configuration. | Weak-field ligands yield high-spin configurations.
|
|
| Count the unpaired electrons. | This configuration has four unpaired electrons. | |
