What is iso field energy in crystal field stabilization energy?
Answers
Answer:
Definition: Crystal Field Stabilization Energy. The Crystal Field Stabilization Energy is defined as the energy of the electron configuration in the ligand field minus the energy of the electronic configuration in the isotropic field.
Explanation:
Factors affecting crystal field splitting energy: 1) The coordination geometry and number of ligands around the metal ion- Generally, the tetrahedral field produce smaller spilling than octahedral field. 2) The nature of the ligands - Strong field ligands cause more splitting than weak field ligands.
Crystal Field Stabilisation Energy (CFSE). Crystal Field Stabilisation Energy (CFSE) For an octahedral complex, an electron in the more stable t2g subset is treated as contributing -2/5Δ whereas an electron in the higher energy eg subset contributes to a destabilisation of +3/5Δ.
When they start bonding with other ligands, the d orbitals split apart and become non-degenerate. This bonding occurs mainly due to different symmetries of the d orbitals and the inductive effect of the ligands on the electrons. The pattern of the splitting of d orbitals depends on upon the nature of crystal field.
