For ∆ > 200 cm−1, a monodentate ligand is expected, whereas for ∆ < 110 cm−1, a bidentate ligand is expected. For a bridging ligand, ∆ is between 110 and 200 cm−1 [31]. Spectra of the complexes (see

• 200 > ∆ > 110 allow us to assume that the substitution of ligands in iron acetylacetonate of the formed oleate complex leads to the bridging type of coordination with some features of the bidentate type.
