A new tetra-homonuclear iron(III) cluster, [Fe4O2(Sal)4(H2O)6]·4DMA·0.75H2O (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 compound crystallizes in the P21/c space group of the monoclinic system with the following unit cell parameters: a= 10.5350(3), b= 11.8840(3), c= 21.7830 (5) (Å), β= 101.536(1)°. Each FeIII atom is six-coordinated in slightly distorted O6 octahedral geometry. 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 Sal2- 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).
