Materials Data on Eu2FeH6 by Materials Project
Eu2FeH6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Eu2+ is bonded to twelve equivalent H1- atoms to form EuH12 cuboctahedra that share corners with twelve equivalent EuH12 cuboctahedra, faces with six equivalent EuH12 cuboctahedra, and faces with four equivalent FeH6 octahedra. All Eu–H bond lengths are 2.58 Å. Fe2+ is bonded to six equivalent H1- atoms to form FeH6 octahedra that share faces with eight equivalent EuH12 cuboctahedra. All Fe–H bond lengths are 1.62 Å. H1- is bonded in a distorted single-bond geometry to four equivalent Eu2+ and one Fe2+ atom.
