Au5Cd8 is gamma-brass structured and crystallizes in the cubic I-43m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 9-coordinate geometry to three equivalent Au(2), three equivalent Cd(1), and six equivalent Cd(2) atoms. In the second Au site, Au(2) is bonded in a 13-coordinate geometry to one Au(2), two equivalent Au(1), two equivalent Cd(1), and eight equivalent Cd(2) atoms. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 6-coordinate geometry to three equivalent Au(1), three equivalent Au(2), and three equivalent Cd(2) atoms. In the second Cd site, Cd(2) is bonded in a 11-coordinate geometry to two equivalent Au(1), four equivalent Au(2), one Cd(1), and four equivalent Cd(2) atoms.
Au5Cd8 is gamma-brass structured and crystallizes in the cubic I-43m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 9-coordinate geometry to three equivalent Au(2), three equivalent Cd(1), and six equivalent Cd(2) atoms. All Au(1)-Au(2) bond lengths are 3.09 Å. All Au(1)-Cd(1) bond lengths are 3.00 Å. There are three shorter (2.88 Å) and three longer (2.89 Å) Au(1)-Cd(2) bond lengths. In the second Au site, Au(2) is bonded in a 13-coordinate geometry to one Au(2), two equivalent Au(1), two equivalent Cd(1), and eight equivalent Cd(2) atoms. The Au(2)-Au(2) bond length is 2.82 Å. Both Au(2)-Cd(1) bond lengths are 2.94 Å. There are two shorter (2.85 Å) and six longer (3.19 Å) Au(2)-Cd(2) bond lengths. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 6-coordinate geometry to three equivalent Au(1), three equivalent Au(2), and three equivalent Cd(2) atoms. All Cd(1)-Cd(2) bond lengths are 2.99 Å.
