substituents within
the secondary coordination sphere of a pincer-based Fe(II) complex
provides Lewis acidic sites capable of binding 1 or 2 equiv of N2H4. Reduction of the 1:1 Fe:N2H4 species affords a rare Fe(NH2)2 complex
in which the amido ligands are stabilized through interactions with
the appended boranes. The NH2 units can be released as
NH3 upon protonation and exchanged with exogenous N2H4.
