Abstract
/Pyropheophytinato a/ iron/III/ chloride [Fe/Pyropheo-a/Cl] and /pyropheophytinato b/ iron/III/ chloride [Fe/Pyropheo-b/Cl] have been prepared and characterized by Mössbauer spectroscopy. The Mössbauer parameters of the iron/III/pyropheophytins are similar to those of iron/III/ porphyrins. A comparison of the quadrupole splittings for the iron/III/ pyropheophytins with those for the iron/III/ pheophytins suggests that the deviations of the cyclopentenone ring and the saturated pyrrole ring from the macrocyclic plane become smaller with the removal of the methoxycarbonyl group.
