Why do compounds having similar geometry have different magnetic moments?
(N/A) The difference in magnetic moment arises due to the presence of weak field and strong field ligands.
If a ligand is strong,the complex formed will be of low spin,and if a ligand is weak,the complex formed is of high spin.
For example,$[CoF_{6}]^{3-}$ is paramagnetic while $[Co(NH_{3})_{6}]^{3+}$ is diamagnetic.
