The synthesis, X-ray crystal structure, electrochemical and spectroscopic properties of NH4Fe2III(bbpmp)(m-SO4)2 1 where bbpmp is the anion of 2,6-bis(2-hydroxy- benzyl)(2-pyridylmethyl)-amino-methyl-4-methylphenol, are reported; this is the first example of a (m-phenolate)(m-SO4)2 complex, with a relevant N,O-donor ligand, as a synthethic analogue for the purple acid phosphatases-sulfate complexes.
