Title: Materials Data on MgH2 by Materials Project

Abstract

MgH2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mg2+ is bonded in a 9-coordinate geometry to seven H1- atoms. There are a spread of Mg–H bond distances ranging from 1.97–2.16 Å. There are two inequivalent H1- sites. In the first H1- site, H1- is bonded to four equivalent Mg2+ atoms to form a mixture of edge and corner-sharing HMg4 tetrahedra. In the second H1- site, H1- is bonded in a 3-coordinate geometry to three equivalent Mg2+ atoms.
