Chapter 21, Problem 8RQ

Interpretation Introduction

Interpretation: The reason for the for the tetrahedral complex ion having different crystal field diagram then octahedral complex ion; tetrahedral crystal field splitting diagram; the reason for tetrahedral complex ions being high spin; and the explanation for the crystal field diagram of square planar complex ion and linear complex ions is to be stated.

Concept introduction: The ratio of crystal field splitting energy of tetrahedral complex and octahedral complex is $\frac{4}{9}$.

The crystal field diagram of square planar complex is obtained by the removal of the two point charges along the $z-\text{axis}$.

The crystal field diagram of linear complex is obtained by the removal of the two point charges along the $z-\text{axis}$ and two along $d_{xy}$.

To determine: The reason for the for the tetrahedral complex ion having different crystal field diagram then octahedral complex ion; tetrahedral crystal field splitting diagram; the reason for tetrahedral complex ions being high spin; and the explanation for the crystal field diagram of square planar complex ion and linear complex ions.
