Synthesis and Structure of the First FeII Heterometallic Alkoxide [(THF)NaFe(OtBu)3]2 − a Possible Precursor for New Materials

The reaction of FeBr2 with three equivalents of NaOtBu in THF affords the first heterometallic FeII alkoxide, [(THF)NaFe(OtBu)3]2 (1), to be structurally characterised. The central core of the structure is an M2O6M′2 fragment with C2 symmetry. The compound is shown to be promising as a new precursor for magnetic iron oxide Fe3O4.
