N2 - The reaction of 1,10′-phenanthroline (phen), tetrasodium pyrophosphate (Na4PPi) and FeCl2·6H2O in deionized water yielded the iron(III)-PPi chelate complex, {[Hphen][Fe(phen)(H2P2O7)2]·2H2O} (1). Although ferric pyrophosphate is used in applications from food to pharmaceuticals, where PPi, acting as an iron chelator, can inhibit growth, be a source of iron, or facilitate iron transfer, there is little structural information on coordination complexes. Herein, the structure of 1 is described, as well as that of the magnetic properties, which confirm the iron in 1 is present as high spin (S = 5/2) Fe(III).
