Iron pentahydride

superconductor. Pairs of hydrogen atoms are not bonded together into molecules. FeH5 has been made by compressing a flake of iron with hydrogen in a diamond anvil cell to a pressure of 130 GPa and heating to below 1500K.[1] When decompressed to 66 GPa it decomposes to solid FeH3
.

The unit cell is tetragonal with space group I4/mmm.[2]
