SrGaAl is half-Heusler structured and crystallizes in the cubic F-43m space group. Sr(1) is bonded in a body-centered cubic geometry to four equivalent Ga(1) and four equivalent Al(1) atoms. Ga(1) is bonded to four equivalent Sr(1) atoms to form GaSr4 tetrahedra that share corners with four equivalent Al(1)Sr4 tetrahedra, corners with twelve equivalent Ga(1)Sr4 tetrahedra, and edges with six equivalent Al(1)Sr4 tetrahedra. Al(1) is bonded to four equivalent Sr(1) atoms to form AlSr4 tetrahedra that share corners with four equivalent Ga(1)Sr4 tetrahedra, corners with twelve equivalent Al(1)Sr4 tetrahedra, and edges with six equivalent Ga(1)Sr4 tetrahedra.
