The material described by Tb(FeZn10)2 crystallizes in the cubic Fd-3m space group. Tb(1) is bonded in a 16-coordinate geometry to four equivalent Zn(1) and twelve equivalent Zn(2) atoms. Fe(1) is bonded to six equivalent Zn(2) and six equivalent Zn(3) atoms to form FeZn12 cuboctahedra that share corners with six equivalent Fe(1)Zn12 cuboctahedra, edges with eighteen equivalent Zn(2)TbZn10Fe cuboctahedra, and faces with six equivalent Zn(2)TbZn10Fe cuboctahedra. There are three inequivalent Zn sites. In the first Zn site, Zn(3) is bonded in a 12-coordinate geometry to two equivalent Fe(1), four equivalent Zn(3), and six equivalent Zn(2) atoms. In the second Zn site, Zn(1) is bonded in a distorted linear geometry to two equivalent Tb(1) and twelve equivalent Zn(2) atoms. In the third Zn site, Zn(2) is bonded to one Tb(1), one Fe(1), two equivalent Zn(1), three equivalent Zn(3), and five equivalent Zn(2) atoms to form distorted ZnTbZn10Fe cuboctahedra that share corners with fifteen equivalent Zn(2)TbZn10Fe cuboctahedra, edges with two equivalent Zn(2)TbZn10Fe cuboctahedra, edges with three equivalent Fe(1)Zn12 cuboctahedra,  a faceface with one Fe(1)Zn12 cuboctahedra, and faces with fifteen equivalent Zn(2)TbZn10Fe cuboctahedra. is represented by the CIF file [CIF]
