Crystal field theory
- According to the crystal field theory, the complex can be classified as high spin or low spin.
- The high spin complex is the compound with the greatest number of unpaired electrons.
- There are fewer unpaired electrons in the low spin complex.
- High spin complexes have low crystal field splitting energy
- Low spin complexes have high crystal field splitting energy.
complex
- In the complex, the center metal atom chromium is in oxidation state.
- The electronic configuration is as follows:
- Only three of the five orbitals are filled, leaving the remaining two for or orbitals.
- Ammonia is a strong field ligand.
- Three orbitals of a metal ion have three unpaired electrons, and all of these orbitals have the same energy.
- Thus, even in the presence of strong ligand, pairing will not occur.
- These hybrids form bonds with ligands ammonia by accepting six lone pairs of electrons, one for each of the six ligands.
