The synthesis and structure of [Fe(Phen)3][(μ-oxo)Fe2Cl6]@DMF are reported. The crystal data for the compound: monoclinic, P2l /c,a =15.491(1),b = 13.217(1),c = 20.748(2)A,β = 93.83(3)°,V = 4239(2)?3,Z = 4,Dc = 1.562g/cm3,μ(MoKα)=1.44 mm-1,F(000)= 2040.0, (C39H31Cl6Fe3N7O2) and Mr = 1009.96. X-ray crystallographic studies reveal that the title compound contains complexes of [Fe(Phen)3]2+ and [Fe2(μ-oxo)Cl6]2- which consists of two [FeCl3] fragments connected by an oxo bridge,with the bond distances of Fe(3)-O(1) 1.744(4) and Fe(2)-O(1) 1.754(4)A,and a bond angle Fe(2)-O(1)-Fe(3) of 162.9(3)°. In the [Fe2(μ-oxo)Cl6]2- complex, the two iron (Ⅲ) centres exhibit tetrahedral coordination, with the distorted tetrahedra formed by three Cl atoms and an oxo bridge. The bond lengths to the donor atoms lie in the range 2.211(1)～2.226(1)A for Fe-Cl, and the non-bonded Fe…Fe distance is 3.459A.
