Chapter 21, Problem 94CP

Interpretation Introduction

Interpretation: Considering z axis to be perpendicular to the plane of the complex, crystal field splitting of trigonal planar complex ion is to be drawn.

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 crystal field splitting diagram of trigonal planar complex ions.
