As originally developed, cystal field theory was used to describe the electronic structure of metal ion crystals, where they are surrounded by oxide ions or other anions that create an electrostatic filed with symmetry dependent on the crystal structure.
If for the complex `K_(4)[FeL_(6)]` the value of `Delta_(0)=22000" "cm^(-1)`. Find out the value of crystal pairing energy. Where L is uninegative monodentate ligand.

A

`-46200" "cm^(-1)`

B

`-52800" "cm^(-1)`

C

`+2200" "cm^(-1)`

D

`-22200" "cm^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B

`K_(4)[overset(+2)FeL_(6)] d^(6) to t_(2g)^(2,2,2)eg^(0,0)`
CFSE`=-0.4xx6Delta_(0)=-2.4Delta_(0)`
`implies "CFSE"=-2.4xx22000=-52800 cm^(-1)`

As originally developed, cystal field theory was used to describe the electronic structure of metal ion crystals, where they are surrounded by oxide ions or other anions that create an electrostatic filed with symmetry dependent on the crystal structure. Total number of nodal planes of the orbitals involved in hybridisation of central metal ion in complex [MnO_(4)]^(-) is :

Read the passage given below and answer the following questions : The crystal field theory (CFT) is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interactions between the metal ion and the ligand. Ligands are treated as point charges in case of anions or dipoles in case of neutral molecules. The five d orbitals in an isolated gaseous metal atom/ion have same energy, i.e., they are degenerate. This degeneracy is maintained if a spherically symmetrical field of negative charges surrounds the metal atom/ ion. However, when this negative field is due to ligands (either anions or the negative ends of dipolar molecules like NH_(3) and H_(2)O ) in a complex, it becomes asymmetrical and the degeneracy of the d orbitals is lifted. It results in splitting of the d orbitals. The CFSE for octahedral [CoCl_(6)]^(4-) is 18,000 cm^(-1) . The CFSE for tetrahedral [CoCl_(4)]^(2-) will be

Valence bond theory for bonding in transition metal complexes was developed by Pauling. From the valence bond point of view, formation of a complex involves reaction between Lewis bases (ligands) and a Lewis acid (metal atom or metal ion) with the formation of coordination covalent (or dative) bonds between them. The model utilizes hybridization of metal s, p and d valence orbitals to account for the observed structures and magnetic properies of complexes. Valence bond theory is able to deal satisfactorily with many stereo chemical and magnetic properies but is has nothing to say about electronic spectra or the reason for the kinetic inertness of chromium (III) and low spin cobalt (III) octahedral complexes. To understand this and more other features of transition metal we must turn to other theories like crystal field theory etc. Pure crystal field theory assumes that the only interaction between the metal ion and the ligands is an electrostatic or ionic one with the ligands being regarded as negative point charges. This theory is quite successful in interpreting many important properties of complexes. Select the correct statement about the crystal field theory.
