AcOF is half-Heusler structured and crystallizes in the cubic F-43m space group. Ac(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent F(1) atoms. O(1) is bonded to four equivalent Ac(1) atoms to form OAc4 tetrahedra that share corners with four equivalent F(1)Ac4 tetrahedra, corners with twelve equivalent O(1)Ac4 tetrahedra, and edges with six equivalent F(1)Ac4 tetrahedra. F(1) is bonded to four equivalent Ac(1) atoms to form FAc4 tetrahedra that share corners with four equivalent O(1)Ac4 tetrahedra, corners with twelve equivalent F(1)Ac4 tetrahedra, and edges with six equivalent O(1)Ac4 tetrahedra.
