Cd11Nd crystallizes in the cubic Pm-3m space group. Nd(1) is bonded in a 20-coordinate geometry to four Cd(4,4); eight equivalent Cd(2); and eight equivalent Cd(3) atoms. There are five inequivalent Cd sites. In the first Cd site, Cd(4) is bonded in a 10-coordinate geometry to one Nd(1), one Cd(1), four equivalent Cd(3), and four equivalent Cd(4) atoms. In the second Cd site, Cd(1) is bonded in a cuboctahedral geometry to twelve Cd(4,4) atoms. In the third Cd site, Cd(2) is bonded in a 9-coordinate geometry to three equivalent Nd(1), three equivalent Cd(2), and three equivalent Cd(3) atoms. In the fourth Cd site, Cd(3) is bonded in a distorted q6 geometry to two equivalent Nd(1), two equivalent Cd(2), two equivalent Cd(3), and four equivalent Cd(4) atoms. In the fifth Cd site, Cd(4) is bonded in a 10-coordinate geometry to one Nd(1), one Cd(1), four equivalent Cd(3), and four equivalent Cd(4) atoms.
