Textbook Problem

Nickel and palladium both form complexes of the general formula M(PR3)2Cl2. (The ligand PR3 is a phosphine such as P(C6H5)3, triphenylphosphine. It is a Lewis base.) The nickel(II) compound is paramagnetic whereas the palladium(II) compound is diamagnetic.

(a) Explain the magnetic properties of these compounds.

(b) How many isomers of each compound are expected?

(a)

Interpretation Introduction

Interpretation: The magnetic property has to be explained.

Concept introduction:

Isomerism: Isomers are compounds with same molecular formula with different arrangements of atoms.

  • Structural isomers:  have same molecular formula but different bonding arrangements of atoms. It is classified into coordination isomer (occurs by exchanging a coordinated ligand and the counter-ions) and linkage isomers (ligand attached through different atoms to the metal).
  • Stereoisomers: differ in their spatial arrangement of atoms.

Paramagnetic property: The presence of unpaired electrons in the electronic configuration of the metal ion in coordination complex.

Diamagnetic property: The absence of unpaired electrons of the metal ion in coordination compound which do repel by the magnet.

Explanation

In the given complex M(PR3)2(Cl)2, the electronic configuration of metal ion is d8, the information tells that the Nickel(II) compound is paramagnetic. Therefore, the square-planar structure never gives paramagnetic with d8 configuration and so the geometry of Nickel(II) compound will be tetrahedral

Interpretation Introduction

Interpretation: The number of possible isomers has to beidentified.
