The structure described by Th6Cd23 crystallizes in the cubic Fm-3m space group. Th(1) is bonded in a 16-coordinate geometry to four equivalent Th(1), four equivalent Cd(2), four equivalent Cd(3), and four equivalent Cd(4) atoms. There are four inequivalent Cd sites. In the first Cd site, Cd(4) is bonded in a 12-coordinate geometry to three equivalent Th(1), three equivalent Cd(2), three equivalent Cd(3), and three equivalent Cd(4) atoms. In the second Cd site, Cd(1) is bonded in a body-centered cubic geometry to eight equivalent Cd(3) atoms. In the third Cd site, Cd(2) is bonded to four equivalent Th(1), four equivalent Cd(3), and four equivalent Cd(4) atoms to form a mixture of corner and face-sharing CdTh4Cd8 cuboctahedra. In the fourth Cd site, Cd(3) is bonded in a 13-coordinate geometry to three equivalent Th(1), one Cd(1), three equivalent Cd(2), three equivalent Cd(3), and three equivalent Cd(4) atoms. is represented by the CIF card [CIF]
