FeNCN and Fe(NCNH)₂: Synthesis, Structure, and Magnetic Properties of a Nitrogen‐Based Pseudo‐oxide and ‐hydroxide of Divalent Iron

Abstract

Iron man challenge: Iron carbodiimide, FeNCN, and its precursor iron (bis)monohydrocyanamide, Fe(NCNH)(2), have been synthesized and physically characterized. Both FeNCN and Fe(NCNH)(2) exhibit nitrogen-mediated antiferromagnetic superexchange interactions with reduced magnetic moments very similar, but not identical, to the correlated 3d oxides.
