Question

The values of the crystal field stabilization energies for a high spin d6 metal ion in octahedral and tetrahedral fields, respectively, are:

Choose an option

Show full solutionCorrect option: A
Correct answer
A−0.4Δo and −0.6Δt

Step-by-step explanation

For d6 configuration, high spin

(i) In case of octahedral complex tgg2.1.1,eg1.1

CFSE=-0.4nt2g+0.6negΔ0+n(P)

=[-0.4×4+0.6×2]Δ0+0

=-0.4Δ0

(i) In case of tetrahedral complex e2,1,t21,1,1

CFSE=-0.6ne+0.4nt2Δr

=[-0.6×3+0.4×3]Δt

=-0.6Δt
