Formation of a novel tetranuclear iron(III) complex with a μ4-PO4 bridge from 4-nitrophenyl phosphate

Abstract

A novel tetranuclear iron(III) complex, [{Fe2(tren)2(µ-O)}2(µ4-PO4)][ClO4]5·2.5H2O 1 [tren = tris(2-aminoethyl)amine], is synthesized; X-ray crystal structure analysis reveals that 1 contains a tetranuclear cation in which the iron atoms are linked by a µ4-PO43– bridge, which is a hydrolytic product from 4-nitrophenyl phosphate.
