Treatment of the chromophore +, where X = Br, I and P4 is the tetradentate open-chain ligand hexaphenyl-1,4,7,10-tetraphosphadecane, with sodium tetrahydroborate under helium or nitrogen gave cationic hydrido- or hydrido-dinitrogen-iron(II) complexes of formula X and X.The structure of the Br * C2H5OH complex was determined from three dimensional X-ray data collected by counter methods.The crystals are triclinic, space group P with cell dimensions a = 15.392(8), b = 16.109(10), c = 9.914(5) Angstroem, α = 69.57(8), β = 78.43(9), γ = 68.46(9) deg.The structure was solved the heavy atom technique to a final conventional R factor of 0.053 over 1631 independent observed reflections.The structure consists of + cations, bromide anions, and solvating C2H5OH molecules.The metal atom is octahedrally coordinated with the four phosphorus atoms of the ligand in the equatorial plane and with the hydrogen atom and one atom of the dinitrogen molecule in the axial positions.
