Au2CdIn2Sn is half-Heusler-derived structured and crystallizes in the trigonal R3m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a body-centered cubic geometry to three equivalent Cd(1), one In(1), three equivalent In(2), and one Sn(1) atom. In the second Au site, Au(2) is bonded in a body-centered cubic geometry to one Cd(1), one In(2), three equivalent In(1), and three equivalent Sn(1) atoms. Cd(1) is bonded to one Au(2) and three equivalent Au(1) atoms to form CdAu4 tetrahedra that share corners with four equivalent In(2)Au4 tetrahedra, corners with six equivalent Cd(1)Au4 tetrahedra, corners with six equivalent Sn(1)Au4 tetrahedra, edges with three equivalent In(1)Au4 tetrahedra, and edges with three equivalent In(2)Au4 tetrahedra.
