Chapter 21, Problem 84AE

 (a)

Interpretation Introduction

Interpretation: The type of isomerism found in $\text{Ru}{\left(\text{phen}\right)}_{\text{3}}^{\text{2+}}$ and the crystal field diagram for the d orbitals in this complex ion is to be stated.

Concept introduction: The electrons in the d orbital of a transition metal split into high and low energy orbitals when ligands are attached to it. The energy difference between these two levels depends upon the properties of both metal and the ligands. If the ligand is strong, then splitting will be high and the complex will be low spin. If the ligand is weak, then splitting will be less and the complex will be high spin.

To determine: The type of isomerism found in $\text{Ru}{\left(\text{phen}\right)}_{\text{3}}^{\text{2+}}$.
