[Pd(F)(Cl)(Br)(I)]2-,has n number of geometrical Isomers. Then, the spin-only magnetic moment and crystal field stabilization energy [CFSE]of [Fe(CN)6]n-6 , respectively,
1.73BMand–2Δ0
2.84BMand–1.6Δ0
0BMand–2.4Δ0
5.92BMand0
Explanation for the correct option:
A: 1.73BMand–2Δ0
[Fe(CN)6]n-6=[Fe(CN)6]3-6=[Fe(CN)6]-3
Fe3+(26)=[Ar]3d5
n=1√n(n+2)=√3=1.73B.MCFSE=(−0.4×nt2g+0.6×neg)Δ0=(−0.4×5+0.6×0)Δ0=-2Δ0
Therefore, Option (A) 1.73BMand–2Δ0 is the correct option.
Consider that a d6 metal ion (M2+) forms a complex with aqua ligands, and the spin only magnetic moment of the complex is 4.9BM. The geometry and the crystal field stabilization energy of the complex is:
