TbCd3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Tb(1) is bonded to twelve Cd(1,1) atoms to form a mixture of face and corner-sharing TbCd12 cuboctahedra. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 12-coordinate geometry to four equivalent Tb(1) and eight Cd(1,1) atoms. In the second Cd site, Cd(1) is bonded in a 12-coordinate geometry to four equivalent Tb(1) and eight Cd(1,1) atoms.
TbCd3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Tb(1) is bonded to twelve Cd(1,1) atoms to form a mixture of face and corner-sharing TbCd12 cuboctahedra. There are six shorter (3.18 Å) and six longer (3.33 Å) Tb(1)-Cd(1,1) bond lengths. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 12-coordinate geometry to four equivalent Tb(1) and eight Cd(1,1) atoms. There are a spread of Cd(1)-Cd(1,1) bond distances ranging from 3.12-3.42 Å. In the second Cd site, Cd(1) is bonded in a 12-coordinate geometry to four equivalent Tb(1) and eight Cd(1,1) atoms. There are two shorter (3.25 Å) and two longer (3.42 Å) Cd(1)-Cd(1) bond lengths.
