Characterization of the FeH Bond in a Three-Coordinate Terminal Hydride Complex of Iron(I)

Characterization of the Fe<img src="http://onlinelibrarystatic.wiley.com/undisplayable_characters/00f8ff.gif" alt="[BOND]">H Bond in a Three-Coordinate Terminal Hydride Complex of Iron(I):

Three’s company: Iron(I) hydride complexes are presented (see picture; N blue, O red) that are the first monomeric open-shell hydride complexes to be crystallographically verified as being three-coordinate at the metal. Backbonding into diketiminate π* orbitals stabilizes the low oxidation state. The FeH bonding has been analyzed using electron-nuclear double resonance (ENDOR).
