Question

Ferrocyanide molecules have the chemical formula Fe (CN) 6 and the iron center is octahedrally coordinated as shown in the figure. The Fe- C distances rFeC = 1.92 Å and the CN distances are rCN = 1.18 Å, and 1 Angstrom is 1 Å = 10-10 m. The individual masses of the atoms that the molecule consists of are mFe = 9.28 ∙ 10-26 kg, mC = 1.99 ∙ 10-26 kg and mN = 2.36 ∙ 10-26 kg.

What is the moment of inertia of Fe (CN) 6 about an axis passing through Fe and two of the CN groups, if the individual atoms are assumed to be point masses?
