MgScGa is half-Heusler structured and crystallizes in the cubic F-43m space group. Mg(1) is bonded to four equivalent Ga(1) atoms to form MgGa4 tetrahedra that share corners with four equivalent Sc(1)Ga4 tetrahedra, corners with twelve equivalent Mg(1)Ga4 tetrahedra, and edges with six equivalent Sc(1)Ga4 tetrahedra. Sc(1) is bonded to four equivalent Ga(1) atoms to form distorted ScGa4 tetrahedra that share corners with four equivalent Mg(1)Ga4 tetrahedra, corners with twelve equivalent Sc(1)Ga4 tetrahedra, and edges with six equivalent Mg(1)Ga4 tetrahedra. Ga(1) is bonded in a body-centered cubic geometry to four equivalent Mg(1) and four equivalent Sc(1) atoms.
