[ Fe (CN)6 ] ^3-and [Fe (CN)6 ]^{4 -} have same structure but opposite magnetic character.

what does opp magnetic char means?

sandeepramesh

means one is paramagnetic (1st one) and the other one (2nd) is diamagnetic :)

eistien

yeah sandeep ramesh is right

see you have Fe3+ in one and Fe2+ in another

Fe3+ has 4s0 3d5 and Fe2+ has 4s0 3d6 so

when pairing up takes place for one i unpaired e- is left for another there is no unpaired e-!!!

Taara

thnx...

should've thought of that......
