ScAgSi is half-Heusler structured and crystallizes in the cubic F-43m space group. Sc(1) is bonded in a body-centered cubic geometry to four equivalent Ag(1) and four equivalent Si(1) atoms. Ag(1) is bonded to four equivalent Sc(1) atoms to form AgSc4 tetrahedra that share corners with four equivalent Si(1)Sc4 tetrahedra, corners with twelve equivalent Ag(1)Sc4 tetrahedra, and edges with six equivalent Si(1)Sc4 tetrahedra. Si(1) is bonded to four equivalent Sc(1) atoms to form SiSc4 tetrahedra that share corners with four equivalent Ag(1)Sc4 tetrahedra, corners with twelve equivalent Si(1)Sc4 tetrahedra, and edges with six equivalent Ag(1)Sc4 tetrahedra.
