The first binuclear iron(III) complex with a terminally coordinated phosphato ligand—a model compound for the oxidized form of purple acid phosphatase from beef spleen

Abstract

Reaction of N,N,N′,N′-tetrakis(2-benzimidazolylmethyl)-2-hydroxy-1,3-diaminopropane dihydrochloride (Htbpo·2HCl) with Fe(ClO₄)₃·9H₂O and diphenylphosphate yields red crystals of [Fe₂Cl₂{O₂P(OPh)₂}(tbpo)(MeOH)](ClO₄)₂·3MeOH; the X-ray structure shows a phosphate ligand terminally coordinated to Fe(2) and a methanol ligand coordinated to Fe(1).
