Question

For the complex ion $\mathrm{Fe}{\left[{\left(\mathrm{CN}\right)}_6\right]}^{-3}$states the type of hybridization.

Answer 1

Hybridization:

1. Hybridization is the process of combining two atomic orbitals to create a new type of hybridized orbitals.
2. In $\mathrm{Fe}{\left[{\left(\mathrm{CN}\right)}_6\right]}^{-3}$complex, because $\mathrm{CN}$ is a strong field ligand, it forms low spin complexes by utilizing inner $3\mathrm{d}$orbitals.
3. Because it has an octahedral shape and six ligands, its hybridization will be ${\mathrm{d}}^2{\mathrm{sp}}^3$.

As a result, $\mathrm{Fe}{\left[{\left(\mathrm{CN}\right)}_6\right]}^{-3}$ is ${\mathrm{d}}^2{\mathrm{sp}}^3$ hybridized.
