Chapter 19, Problem 42E

Interpretation Introduction

Interpretation: The geometrical and linkage isomers of ${\text{Co(NH}}_{\text{3}}{\text{)}}_{\text{4}}{{\text{(NO}}_{\text{2}}\text{)}}_{\text{2}}$ needs to be determined.

Concept Introduction:

A metal complex can be shownas ${\text{[ML}}_{\text{n}}\text{]}$ . Here M indicates the metal atom or ion whereas L indicates the ligands which are present in ‘n’ numbers. The coordination number define the number of coordinate bonds between metal and ligand.

Geometrical isomers are the type of stereoisomers which can be defined as the complexes or molecules which have same structural formula but different orientation of bonded ligands in the plane.

Linkage isomers are a type of structural isomers in which the bonded ligands are ambidentate ligands and have different bonding atoms which form coordination bond with metal ion. Some common examples of ambidentate ligands areSCN- and NO2-.
