Abstract

Mossbauer, EPR, magnetic susceptibility, and DFT studies of the unusual two-coordinate iron (II) amide Fe[N(t-Bu) 2] 2 show that it retains a linear N-Fe-N framework due to the nonbonding δ nature of the (xy, x 2-y 2) orbitals. The resulting near-degenerate ground state gives rise to a large magnetic moment and a remarkably large internal hyperfine field. The results confirm that extraordinary orbital magnetic effects can arise in linear transition metal complexes in which orbital degeneracies are not broken by Jahn-Teller or Renner-Teller distortions.
