Iron pentahydrideFeH5 is asuperhydride compound ofiron andhydrogen, stable under high pressures. It is important because it contains atomic hydrogen atoms that are not bonded into smaller molecular clusters, and may be asuperconductor. Pairs of hydrogen atoms are not bonded together into molecules.FeH5 has been made by compressing a flake of iron with hydrogen in adiamond anvil cell to a pressure of 130 GPa and heating to below 1500K.[1] When decompressed to 66 GPa it decomposes to solidFeH3.
