Which is high spin complex

A

`[CoF_6]^(3-)`

B

`[Fe(CN)_6]^(3-)`

C

`[Fe(CN)_6]^(4-)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
More the unpaired , `e^-` more will be the spin pairing takes place in presence of strong field, in presence of weak field `F^-` unpaired `e^-` will be more.
`therefore [CoFe_6]^(3-)` is high spin complex.
