Materials Data on Mg(ScGa)2 by Materials Project

Mg(ScGa)2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Mg is bonded in a square co-planar geometry to four equivalent Ga atoms. All Mg–Ga bond lengths are 2.82 Å. Sc is bonded in a 6-coordinate geometry to six equivalent Ga atoms. There are two shorter (2.84 Å) and four longer (2.92 Å) Sc–Ga bond lengths. Ga is bonded in a 9-coordinate geometry to two equivalent Mg, six equivalent Sc, and one Ga atom. The Ga–Ga bond length is 2.55 Å.
