EuAu5Cd crystallizes in the monoclinic C2 space group. Eu(1) is bonded to three equivalent Au(1), three equivalent Au(2), and six equivalent Au(3) atoms to form a mixture of distorted face and edge-sharing EuAu12 cuboctahedra. There are four inequivalent Au sites. In the first Au site, Au(1) is bonded in a 11-coordinate geometry to three equivalent Eu(1), two equivalent Au(2), two equivalent Au(3), two equivalent Au(4), and two equivalent Cd(1) atoms. In the second Au site, Au(2) is bonded in a 11-coordinate geometry to three equivalent Eu(1), two equivalent Au(1), two equivalent Au(3), two equivalent Au(4), and two equivalent Cd(1) atoms. In the third Au site, Au(3) is bonded in a 11-coordinate geometry to three equivalent Eu(1), one Au(1), one Au(2), two equivalent Au(3), two equivalent Au(4), and two equivalent Cd(1) atoms. In the fourth Au site, Au(4) is bonded in a linear geometry to two equivalent Au(1), two equivalent Au(2), four equivalent Au(3), and two equivalent Cd(1) atoms. Cd(1) is bonded in a 10-coordinate geometry to two equivalent Au(1), two equivalent Au(2), two equivalent Au(4), and four equivalent Au(3) atoms.
