Graphical Abstract: A new tetra-homonuclear iron(III) cluster, [Fe
4O
2(Sal)
4(H
2O)
6]·4DMA·0.75H
2O, where Sal= salicylic acid and DMA=
N,
N-dimethylacetamide consolidated
via two
µ3-oxo- and four salicylate-bridges was synthesized and characterized by IR spectroscopic method as well as by single crystal X-ray diffraction analysis. The structure of the obtained tetranuclear compound consists of four FeIII atoms in a “butterfly” arrangement. The coordination sphere of each of the two central FeIII atoms is generated by two
μ3-oxo-bridging atoms and four oxygen atoms provided by the tridentate-bridging Sal
2- ligands, while the coordination polyhedron of another two iron atoms involve six oxygen atoms from three water molecules, two salicylic and one
μ3-oxigen atom. The Fe-O distances within Fe-O-Fe bridge are of 2.102(3) Å (for wing-body) and 2.038(3) Å (for body-body).
