Title: Materials Data on EuH2 by Materials Project

Abstract

EuH2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Eu2+ is bonded in a 3-coordinate geometry to eleven H1- atoms. There are a spread of Eu–H bond distances ranging from 2.29–2.78 Å. There are two inequivalent H1- sites. In the first H1- site, H1- is bonded to six equivalent Eu2+ atoms to form HEu6 octahedra that share corners with twelve equivalent HEu6 octahedra, corners with twelve equivalent HEu5 trigonal bipyramids, edges with six equivalent HEu6 octahedra, faces with two equivalent HEu6 octahedra, and faces with six equivalent HEu5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 51°. In the second H1- site, H1- is bonded to five equivalent Eu2+ atoms to form HEu5 trigonal bipyramids that share corners with twelve equivalent HEu6 octahedra, corners with eight equivalent HEu5 trigonal bipyramids, edges with six equivalent HEu5 trigonal bipyramids, and faces with six equivalent HEu6 octahedra. The corner-sharing octahedra tilt angles range from 29–60°.
