Extended metal atom chain (EMAC) complexes of first-row transition metals with metal-metal bonds have the potential to elicit unique magnetic properties and reactivities. Until now, the library of EMAC complexes with late-first-row transition metals was incomplete because of the omission of a triiron species with Fe-Fe bonding. Herein we report the synthesis and preliminary investigation of the first linear, triiron(II) complex containing close Fe-Fe interactions. The complex is supported by three dianionic 2,6-bis[(trimethylsilyl)amido]pyridine ligands (L), with an overall composition of Fe3L3, and pseudohelical ligand coordination stabilizing the local trigonal-planar geometry at each iron. Fe3L3 was characterized by X-ray diffraction, 1H NMR, cyclic voltammetry, electronic absorption, and Mossbauer spectroscopies. Evans method anal. indicated a large uncompensated spin and an S = 6 ground state, suggesting ferromagnetic coupling in the triiron chain, likely due to direct exchange. The first structurally characterized triiron extended metal atom chain complex is presented. The complex is composed of three ferrous ions supported by three 2,6-bis[(trimethylsilyl)amido]pyridine ligands. The iron atoms are arranged linearly with two sym. Fe-Fe bonds of 2.437 Å indicative of modest single bonds. In the part of experimental materials, we found many familiar compounds, such as 2,6-Diaminopyridine(cas: 141-86-6COA of Formula: C5H7N3)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.COA of Formula: C5H7N3
