The hybridization for the complex ion [FeF6]3- and [Fe(CN)6]3- is :
sp3d2 and d2sp3
Fe3+ = 3d5 in both complexes
F- is a weak field ligand: no pairing, five unpaired electrons, outer 4s, 4p, 4d orbitals used = sp3d2 (high spin)
CN- is a strong field ligand: electrons pair to t2g5, two inner 3d orbitals freed = d2sp3 (low spin)
Hence, sp3d2 and d2sp3.
