Textbook Problem

What types of isomers are possible for the following compounds or complex ions?

(a) K[Co(NH3)2Cl4]

(b) Pt(en)Cl2 (square-planar)

(c) [Co(NH3)5Cl]2+

(d) [Ru(phen)3]Cl3

(e) Na2[MnCl4] (tetrahedral)

(f) [Co(NH3)5NO2)2+

(a)

Interpretation Introduction

Interpretation: The type of isomers that are possible for the given complex has to be determined.

Concept introduction:

Geometric isomers are stereoisomers that cannot be interconverted without breaking the chemical bonds. Cis–trans and fac-mer are types of geometrical isomers. In Cis–trans isomers, identical ligands located at adjacent to each other for cis and anti to each other for trans. In fac-mer isomers, three identical ligands are lying at the corners of a triangular face for fac and identical ligands are lying at meridian for mer.

Complexes showing Cis–trans geometrical isomerism are tetrahedral, square planar and octahedral of type,

  Ma2b2 MmetalMa2bc a,b,cligandsMa4b2

Complexes showing fac-mer isomerism are in a type of MA3B3 (octahedral).

Optical isomers: Optical isomers are non-superimposable mirror images.

Structural isomers are having same ligands but the atom linked for ligand to metal is different these isomers.

Explanation

In K[Co(NH3)2Cl4] complex is given below,
