The hydrido complex [FeH6]4- has Oh symmetry. The bonding in [FeH6]4- can be described in term of the interaction between the atomic orbital of Fe and the LGOs of the H6-fragment.

(a) Derive the six LGOs of the H6 fragments showing clearly how you determine their symmetries.

B) The bais set for the Fe atom consists of valence 3d, 4s and 4p orbitals. Determine the symmetries of these orbitals under Oh symmetry.

(c) Construct an MO diagram for the formation of [FeH6]4- from Fe and the H6- fragment Showing which MOs are occupied. Comment on the characters of the MOs. How Does this bonding picture differ from that of SF6?
