The structure described by AuNi2Sn4 crystallizes in the trigonal R-3m space group. Ni(1) is bonded in a body-centered cubic geometry to one Au(1), three equivalent Sn(2), and four equivalent Sn(1) atoms. Au(1) is bonded in a distorted body-centered cubic geometry to two equivalent Ni(1) and six equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to four equivalent Ni(1) atoms to form a mixture of distorted corner and edge-sharing SnNi4 tetrahedra. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to three equivalent Ni(1) and three equivalent Au(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
