Exchange interactions in a series of novel heteronuclear basic carboxylate complexes containing two iron(III) ions and a divalent metal ion
Abstract
Complexes [Fe2IIIMIIO(MeCO2)6py3]py (M = Mg, Mn, Co, Ni, or Zn; py = pyridine), isomorphous(except for M = Ni) with the mixed-valence compounds [M3O(MeCO2)6py3]py (M = Mn or Fe), are reported; their magnetic properties provide new information about superexchange pathways in the trinuclear basic carboxylate system.
