Chapter 21, Problem 21.11P

Interpretation Introduction

Interpretation:

Draw the possible diastereoisomers for the below compound:

${\left[\text{Cr}{\left(\text{en}\right)}_2{\text{Cl}}_2\right]}^{+}$

Concept introduction:

Diastereoisomers are the stereoisomers which are non-superimposable, non-mirror images. In general, square planar complexes of the type MA₂B₂ and MA₂BC present as diastereoisomers (trans and cis isomers), no isomer is also available MA₂B₂ complexes. Here M is metal ion and A, B, and C are ligands.

In cis isomers, the identical ligands are residing in adjacent corners of the square.

In trans-isomers, the identical glands are opposite to each other.

Octahedral complexes of the type MA₄B₂ exist as diastereoisomers.
