Materials Data on Mg2H4Ru by Materials Project
Mg2RuH4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Mg is bonded in a 2-coordinate geometry to eight H atoms. There are a spread of Mg–H bond distances ranging from 2.11–2.43 Å. Ru is bonded in a distorted rectangular see-saw-like geometry to four H atoms. There is two shorter (1.67 Å) and two longer (1.70 Å) Ru–H bond length. There are two inequivalent H sites. In the first H site, H is bonded to four equivalent Mg and one Ru atom to form a mixture of distorted edge, face, and corner-sharing HMg4Ru square pyramids. In the second H site, H is bonded to four equivalent Mg and one Ru atom to form a mixture of distorted edge, face, and corner-sharing HMg4Ru square pyramids.
