Abstract

Aerobic oxidation of (tmeda)Fe(CH₂^tBu)₂ in toluene or THF solution leads to the self-assembly of a magic-sized all-ferrous oxide cluster containing the Fe₉O₆ subunit and bearing organometallic and diamine ligands. Mössbauer studies of the cluster are consistent with an all-ferrous assignment and magnetometry reveals complex intracluster and intercluster magnetic interactions.
