Abstract
In the centrosymmetric dimeric title complex, [Fe2(C14H10N2O4)2Cl2(C2H6OS)2]·2C2H6OS, two {Fe(L)Cl(DMSO)} units (L is the tridentate ligand 4-nitro-2-{[2-(oxidomethyl)phenyl]iminomethyl}phenolate; DMSO is dimethyl sulfoxide) are bridged by two O atoms, with an Fe⋯Fe separation of 3.1838 (8) Å. The coordination polyhedron of the FeIII atoms can be described as distorted octahedral, with four Fe—O, one Fe—N and one Fe—Cl coordination bonds. The L ligand is not planar, the dihedral angle between the 2-(oxidomethyl)phenyl]imino and 4-nitro-2-(iminomethyl)phenolate planes being 48.54 (9)°. The solvent DMSO molecule is disordered over two orientations with equal occupancy.
