For the octahedral complexes ofFe3+inSCN-(thiocyanato-S) and inCN-ligand environments, the difference between the spin-only magnetic moments in Bohr magnetons (when approximated to the nearest integer) is
[Atomic number of Fe = 26]

Question diagram: For the octahedral complexes of F e 3 + in S C N - (thiocyan
Answer:
4.00
Solution:

SCN-is weak field effect (WFE) ligand whereasCN-is strong field effect (SFE) ligand.


Spin only magnetic moment=5(5+2)=35 BM


Spin only magnetic moment=1(1+2)=3 BM
Difference=35-3 4
