The material structure described by TbGe2 crystallizes in the tetragonal I4_1/amd space group. Tb(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of distorted edge and face-sharing TbGe12 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Ge(1) atoms. is represented by the CIF card [CIF]
