Abstract

original image

One monodentate and two bidentate carboxylato ligands link the central FeII ion in the cation of 1 (shown on the right) with each of the three neighboring FeII ions. This arrangement results in a complex with threefold symmetry and weak ferromagnetic interactions between the iron centers. Such aggregates may be important in the initial stages of ferritin core formation in the absence of dioxygen. Hbpg = N,N-bis(2-pyridylmethyl)glycine.
