Materials Data on Li2MgH4 by Materials Project
Abstract
Li2MgH4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Li1+ is bonded to six H1- atoms to form distorted LiH6 octahedra that share corners with four equivalent LiH6 octahedra, corners with four equivalent MgH6 octahedra, edges with two equivalent LiH6 octahedra, edges with two equivalent MgH6 octahedra, and faces with two equivalent LiH6 octahedra. The corner-sharing octahedra tilt angles range from 38–61°. There are a spread of Li–H bond distances ranging from 1.92–2.14 Å. Mg2+ is bonded to six H1- atoms to form MgH6 octahedra that share corners with eight equivalent LiH6 octahedra, edges with two equivalent MgH6 octahedra, and edges with four equivalent LiH6 octahedra. The corner-sharing octahedra tilt angles range from 48–61°. All Mg–H bond lengths are 1.96 Å. There are two inequivalent H1- sites. In the first H1- site, H1- is bonded to four equivalent Li1+ and one Mg2+ atom to form distorted HLi4Mg trigonal bipyramids that share corners with five equivalent HLi4Mg trigonal bipyramids, corners with four equivalent HLi2Mg2 trigonal pyramids, edges with four equivalent HLi4Mg trigonal bipyramids, and edges with four equivalent HLi2Mg2 trigonal pyramids. In the second H1- site, H1- is bonded to two equivalent Li1+ and two equivalent Mg2+ atomsmore »
