Chapter 9, Problem 9C.15E

Interpretation Introduction

Interpretation:

The possible isomers of the complex $\left[\text{Cr}{\left({\text{NH}}_{\text{3}}\right)}_{\text{5}}\left({\text{NO}}_{\text{2}}\right)\right]{\text{Cl}}_{\text{2}}$ have to be given.

Concept Introduction:

Isomers:

The compounds with same molecular formula but differ in the arrangement of the atom are said to be isomers.

Linkage isomers:

Linkage isomerism occurs with ambidentate ligands that are capable of coordinating in more than one way.

Example:

${\text{SCN}}^{\text{-}}{\text{/NCS}}^{\text{-}}$.  The only difference is the atoms bind to the central ion.  The ligand must have more than one donor atom but bind to ion in only one place.
