The trihydride complex [FeH3(dmpe)2]+ (dmpe = Me2PCH2CH2PMe2) is best represented as [FeH(H2)(dmpe2]+, with the H-H separation in the H-2 being ca. 0.81 angstrom. The H-2 can be replaced by N2, CO, MeCN, MeNC and C2H4. The dinitrogen complex [FeH(N2)(dmpe)2]+ may be deprotonated to yield the solution-stable, trigonal-bipyramidal species [Fe(N2)(dmpe)2], which can be reprotonated by HCl to yield [FeCl2(dmpe)2], N2, H-2, and NH3. The crystal structures of [FeH(H2)(dmpe)2]BPh4 and [FeH(N2)(dmpe)2]BPh4 have been determined.
