trans-Chlorobis[ethylenebis(diethylphosphine-P)]hydridoiron(II), [FeHCl(depe)2] (depe = C10H24P2), has been prepared from [FeCl2(depe)2] and sodium-naphthalene in tetrahydrofuran solution under nitrogen. The structural characterization of the title compound represents the first of an iron(II) hydride halide complex having a P4 donor set. The Fe centre is surrounded by one hydride ligand, one Cl atom, trans to the hydride, and two bis(phosphine) ligands within a distorted octahedron. The trans geometry has also been confirmed in solution by NMR spectroscopy.
