Abstract

The reaction of Fe(BF ₄ ) ₂ ·6H ₂ O and one equivalent of HC(3,5-Me ₂ pz) ₃ in acetonitrile leads to the formation of {Fe[HC(3,5-Me ₂ pz) ₃ ](H ₂ O) ₃ } (BF ₄ ) ₂ . The solution phase ¹ H NMR spectrum is broad with chemical shifts ranging from 54 to -42 ppm, a range that is indicative of a paramagnetic high-spin complex. Magnetic moment measurements show that the complex is paramagnetic in the solid-state with μ _eff = 4.89μ _B . The solid-state structure shows the N ₃ FeO ₃ central core is a distorted octahedron with N-Fe-N angles averaging 84.4° and O-Fe-O angles averaging 90.0°. The average Fe-N distance is 2.18 Å and the average Fe-O bond distance is 2.12 Å. Mössbauer spectra, obtained at 78 and 295 K, clearly reveal that this complex is high-spin at these temperatures with hyperfine parameters typical of a pseudooctahedral iron(II) complex.
