X-ray and electronic structure of tris(benzoylacetonato-κ2O,O′)iron(III)

Abstract

Solid state crystal data of d5 tris(benzoylacetonato-κ2O,O′)iron(III), [Fe(ba)3], are presented. The mer isomer crystallized in the solid state. Density functional theory calculations show that both fac and mer isomers of [Fe(ba)3] can exist. Both fac and mer [Fe(ba)3] are high spin d5 complexes with the same ordering of the d-based molecular orbitals in order of increasing orbital energy, namely dxy < dyz ≈ dxz < dz2 ≈ dx2-y2.
