Of central importance to elucidating iron's role in biol. nitrogen fixation are the accessible geometries and
oxidn. states of proposed iron intermediates. Our group has an ongoing interest in exploring the chem. of Fe-
N_xH_y species and have successfully described terminal imide and nitride species supported by anionic
tris(phosphino)borate ligands as well as terminal N_2 complexes stabilized by anionic tris(phosphino)silyl
ligands in pseudo-tetrahedral and trigonal-bipyramidal geometries, resp. A single ligand scaffold capable of
stabilizing low-valent complexes with a π-acidic N_2 mol., as well as high-valent complexes with a π-basic
nitride ligand would certainly be of interest; accordingly, the synthesis of a series of iron complexes
supported by the neutral tris(phosphino)borane ligand, [TPB^R] ([TPB^R] = (o-(R_2P)C_6H_4)_3B), R = iPr, Ph) will
be presented and their structures and chem. reactivity discussed within the context of the hemi-lability of the
apical Lewis-acidic borane.
