Abstract

The synthesis and structural characterization is reported for [Fe(dien)₂][FeSe₂]₂ and [Fe(tren)][FeSe₂]₂, two new mixed-valence compounds that contain infinite _∞¹(FeSe₂) tetrahedral chains separated by Fe–amine complexes. The inter- and intra-chain magnetic interactions can be controlled by changing the denticity of the amine while preserving the general structural motif.
