Materials Data on MgGa2 by Materials Project
MgGa2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Mg is bonded to five equivalent Mg and seven Ga atoms to form a mixture of distorted corner, edge, and face-sharing MgMg5Ga7 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 2.92–3.19 Å. There are a spread of Mg–Ga bond distances ranging from 3.00–3.07 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 12-coordinate geometry to three equivalent Mg and seven Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.88–3.01 Å. In the second Ga site, Ga is bonded in a 12-coordinate geometry to four equivalent Mg and six Ga atoms. The Ga–Ga bond length is 2.85 Å.
