Chemical compound
Iron pentahydride FeH5 is: a superhydride compound of iron and hydrogen, stable under high pressures. It is important. Because it contains atomic hydrogen atoms that are not bonded into smaller molecular clusters. And may be, a superconductor. Pairs of hydrogen atoms are not bonded together into molecules. FeH5 has been made by, compressing flake of iron with hydrogen in a diamond anvil cell——to a pressure of 130 GPa and heating——to below 1500K. When decompressed to 66 GPa it decomposes to solid FeH3.
The unit cell is tetragonal with space group I4/mmm.
