The field of bioinorganic chemistry is at a propitious stage of development. Ever more
complex metallobiomolecules are isolated and purified, physical methodologies and …

1. INTRODUCTION Stable, open-shell (d1− d9) transition metal complexes in which the
metal is two-coordinate or quasi-two-coordinate are among the rarest and least investigated …

These can be considered substituted versions of all-iron 36. Although MFe3S4 cores depart
from the familiar and efficient idealized symmetry of the Fe4S4 cubane structure, the …

Metalloenzymes catalyze many difficult and critical reactions in biological systems. 1 The
ability of these biological catalysts to perform these reactions under mild conditions with …

Cyclic alkyl (amino) carbene stabilized two-and three-coordinate Fe (I) complexes,(cAAC)
2FeCl (2) and [(cAAC) 2Fe][B (C6F5) 4](3), respectively, were prepared and thoroughly …

Alternating current magnetic investigations on the trigonal-planar high-spin Co2+ complexes
[Li (15-crown-5)][Co {N (SiMe3) 2} 3],[Co {N (SiMe3) 2} 2 (THF)](THF= tetrahydrofuran), and …

57Fe electric and magnetic hyperfine parameters were calculated for a series of 10 iron
model complexes, covering a wide range of oxidation and spin states. Employing the B3LYP …

Three-coordinate organometallic complexes are rare, especially with the prototypical methyl
ligand. Using a hindered, rigid bidentate ligand (L), it is possible to create 12-electron …

The MN S= 3/2 resting state of the FeMo cofactor of nitrogenase has been proposed to have
metal-ion valencies of either Mo4+ 6Fe2+ Fe3+ (derived from metal hyperfine interactions) …

Mössbauer spectra of [LFeIIX] 0 (L= β-diketiminate; X= Cl-, CH3-, NHTol-, NHtBu-), 1. X,
were recorded between 4.2 and 200 K in applied magnetic fields up to 8.0 T. A spin …
