The material structure described by TbCBi2 crystallizes in the tetragonal P4_2/mbc space group. Tb(1) is bonded in a 2-coordinate geometry to two equivalent C(1), two equivalent Bi(2), and four equivalent Bi(1) atoms. C(1) is bonded in a 6-coordinate geometry to two equivalent Tb(1) and four equivalent Bi(2) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to four equivalent Tb(1) and two equivalent Bi(1) atoms. In the second Bi site, Bi(2) is bonded in a 6-coordinate geometry to two equivalent Tb(1) and four equivalent C(1) atoms. is represented by the CIF file [CIF]
