The relationship between the crystal field splitting energy in a tetrahedral field () and an octahed — Coordination Compounds Chemistry Question
Question
The relationship between the crystal field splitting energy in a tetrahedral field ($\Delta_t$) and an octahedral field ($\Delta_o$) formed by the same metal and ligands is given by:
Answer: C
💡 Solution & Explanation
Because a tetrahedron has only 4 ligands (compared to 6 in an octahedron) and they do not point directly at the d-orbitals, the splitting is significantly weaker. The exact relationship is $\Delta_t = \frac{4}{9} \Delta_o$.
