摘要：

The recently synthesized FeH5 at high pressure is calculated to be a superconductor with a critical temperature (T-c) of 51 K at 130 GPa. The crystal structure of this compound can be described as stacking bilayers of a puckered hexagonal honeycomb of H atoms sandwiched between slabs of atomic Fe and H atoms. The honeycomb layers resemble the predicted structure of a metallic and high T-c Cmca phase of solid hydrogen. Electron-phonon interactions were mainly derived from coupling of the electronic bands with bending vibrations of the hydrogens in the puckered layers.
