In what way `[FeF_(6)]^(4-)` differs from `[Fe (CN)_6]^(4-)`.

Mention the type of hybridisation and magnetic property of the following complexes using VB theory a) [FeF_6]^(4-) b) [Fe(CN)_6]^(4-)

The geometry of complex ion [Fe (CN)_6]^(4-) is

On the basis of following E^(@) values , the strongest oxidising agent is [Fe(CN)_(6)]^(4-)to[Fe(CN)_(6)]^(3-)+e^(-)E^(@)=-0.35V Fe^(2+)toFe^(3+)+e^(-) " " E^(@)=-0.77V

The complex [CoF_6]^(4-) is :

[Fe F_6]^(4-) is paramagnetic because

In the complexes [Fe(H_(2)O)_(6)]^(3+), [Fe(CN)_(6)]^(3-), [Fe(C_(2)O_(4))_(3)]^(3-) and [FeCl_(6)]^(3-) , more stability is shown by
