Abstract The X-ray crystal structure of trinuclear iron acetate [Fe3O(CH3COO)6(H2O)3]2 [ZnCl4] ⋅ 2H2O was determined. The crystal has a ionic structure. It is monoclinic, a = 25.363(7), b = 14.533(4), c = 15.692(4) Å, β = 103.11(2)°, space group C2/c, and R = 0.0685. The structure of the cationic complex [Fe3O(CH3COO)6(H2O)3]+ is typical of trinuclear iron(III) compounds containing a μ3-O bridge: the iron atoms are situated at the vertices of an almost equilateral triangle with the O atom at the center. Each Fe atom is coordinated by four O atoms of bridging carboxy groups, the μ3-bridging O atom, and the water molecule in the trans position to the latter O atom. Mössbauer spectroscopy evidence indicates the high-spin state (S = 5/2) of the iron(III) ions.
