Abstract
STABLE hydrido-complexes of the type trans-[MHX(phosphine)n] (X = halogen or similar anionic ligand, phosphine = tertiary phosphine or chelate di-tertiary phosphine) containing the heavier transition metals ruthenium1, osmium1, palladium2 and platinum2 have been reported and a very unstable nickel derivative is also known3. Here we report the first stable derivatives containing a metal (iron) from the first transition series. These are interesting because the halo-hydrides (II) and (IV) show enormous chemical shifts in the proton resonance spectrum and because the hydride (I) was prepared from the metal and gaseous hydrogen. They have the trans-octahedral structure shown below and their properties are summarized in Table 1.
