μ-Oxo-bis[N ,N '-o-phenylene-di(salicylaldiminato)iron(III)] was synthesized in dioxane solvent and its crystal structure determined. [C2OH14N ,OiFe]-,O · (C4H8O2), monoclinic, space group P21/ c ,a = 14.650(2), b = 18.990(1), c = 13.296(1) Å, β = 76.080(7), V = 3590.3 Å3, Z = 4. Two iron (III) atoms in square pyramidal pentacoordination are bridged by an oxygen atom with an Fe - O - Fe angle of 145 and a Fe-Fe distance of 3.409(1) Å. The iron (III) centers are antiferrommagnetically coupled (J
