The compound described by Sc2Au2Sn crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Sn(1) atoms. In the second Sc site, Sc(2) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Sn(1) atoms. Au(1) is bonded in a 8-coordinate geometry to three equivalent Sc(1), three equivalent Sc(2), and two equivalent Sn(1) atoms. Sn(1) is bonded in a 12-coordinate geometry to four equivalent Sc(1), four equivalent Sc(2), and four equivalent Au(1) atoms. is represented by the CIF card [CIF]
