The material structure described by Na6Au7Cd16 crystallizes in the cubic Fm-3m space group. Na(1) is bonded in a 12-coordinate geometry to four equivalent Au(2), four equivalent Cd(1), and four equivalent Cd(2) atoms. There are two inequivalent Au sites. In the first Au site, Au(2) is bonded to four equivalent Na(1), four equivalent Cd(1), and four equivalent Cd(2) atoms to form a mixture of distorted face and corner-sharing AuNa4Cd8 cuboctahedra. In the second Au site, Au(1) is bonded in a body-centered cubic geometry to eight equivalent Cd(1) atoms. There are two inequivalent Cd sites. In the first Cd site, Cd(2) is bonded in a 6-coordinate geometry to three equivalent Na(1) and three equivalent Au(2) atoms. In the second Cd site, Cd(1) is bonded in a 7-coordinate geometry to three equivalent Na(1), one Au(1), and three equivalent Au(2) atoms. is represented by the CIF file [CIF]
