Abstract

In this work, an Fe3O triangle based helical chain complex [Fe33-O)(μ-O2CH)6H2O] was assembled in a solvothermal reaction. The complex was a rare polymeric complex bearing charge separation of Fe3+ and Fe2.5+, in which the charge distribution was like that of magnetite. The valence distribution and polymeric nature result in various magnetism behaviours e.g., ferrimagnetism along the chain, canted antiferromagnetic order, spin-flop and field induced SCM like behavior at low temperature.
