Materials Data on Mg2Ga5 by Materials Project
Mg2Ga5 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Mg is bonded in a 10-coordinate geometry to ten Ga atoms. There are a spread of Mg–Ga bond distances ranging from 2.88–3.00 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 8-coordinate geometry to four equivalent Mg and four Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.62–2.69 Å. In the second Ga site, Ga is bonded in a 9-coordinate geometry to four equivalent Mg and five Ga atoms. The Ga–Ga bond length is 3.03 Å.
