Abstract

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 Fe[BOND]H bonding has been analyzed using electron-nuclear double resonance (ENDOR).
