Question

How is the crystal field splitting energy for octahedral complex (\(\Delta_o\)) related to that of tetrahedral complex (\(\Delta_t\))?

Hint:

- Octahedral complexes experience a larger splitting of d-orbitals compared to tetrahedral complexes. - The ratio of \(\Delta_t\) to \(\Delta_o\) is derived based on their geometry and ligand interactions.

Answer 1

The crystal field splitting energy for octahedral complex (\(\Delta_o\)) is related to that of the tetrahedral complex (\(\Delta_t\)) by the following equation: \[ \Delta_t = \left(\frac{4}{9}\right) \Delta_o \] This relation arises due to the difference in the ligand field splitting between the two geometries.
