Chapter 21, Problem 2ALQ

Interpretation Introduction

Interpretation: The diamagnetic and paramagnetic nature of two metal complexes is given. The shape of both the complexes is to be determined.

Concept introduction:  The strong-field ligands lead to pairing of electrons and lead to diamagnetic species, while the low-field ligand do not have tendency to pair up the electrons and therefore forms paramagnetic species.

To determine: The shape of the given complexes ${\left[\text{Ni}{\left({\text{NH}}_3\right)}_4\right]}^{2+}$ and ${\left[\text{Ni}{\left(\text{SCN}\right)}_4\right]}^{2-}$.
