The structure described by ThCd5 crystallizes in the hexagonal P6_3/mmc space group. Th(1) is bonded in a 14-coordinate geometry to two equivalent Cd(2), two equivalent Cd(4), four equivalent Cd(3), and six equivalent Cd(5) atoms. There are five inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 6-coordinate geometry to six equivalent Cd(5) atoms. In the second Cd site, Cd(2) is bonded in a 6-coordinate geometry to three equivalent Th(1), three equivalent Cd(3), three equivalent Cd(4), and three equivalent Cd(5) atoms. In the third Cd site, Cd(3) is bonded to four equivalent Th(1), two equivalent Cd(2), two equivalent Cd(4), and four equivalent Cd(5) atoms to form a mixture of face and corner-sharing CdTh4Cd8 cuboctahedra. In the fourth Cd site, Cd(4) is bonded in a 12-coordinate geometry to two equivalent Th(1), two equivalent Cd(2), two equivalent Cd(3), two equivalent Cd(4), and four equivalent Cd(5) atoms. In the fifth Cd site, Cd(5) is bonded in a 12-coordinate geometry to three equivalent Th(1), one Cd(1), one Cd(2), two equivalent Cd(3), two equivalent Cd(4), and three equivalent Cd(5) atoms. is represented by the CIF file [CIF]
