Crystal structure and magnetic characterization of mu(6)-oxo bridged Hexanuclear Fe(III) complex

Abstract

In this study, the synthesis, X-ray crystal structure and magnetic properties of a new hexanuclear Fe(III) complex, 2[OFe6(thme)(4)Cl-6].4[C6H15N].6[H2O] (1), (H(3)thme = 1,1,1-Tris(hydroxymethyl)ethane) is reported. The structure of 1 is described as the hexametalate core [OFe6(thme)(4)Cl-6] consisting of an octahedral arrangement by four alkoxo oxygen atom from thme ligand, a terminal chloride atom and one mu(6)-oxo group at the center. Variable-temperature magnetic susceptibility measurements of 1 indicate an antiferromagnetic interaction between the Fe(III) centers.
