The crystal structure described by Tb3Ge5 crystallizes in the hexagonal P-62c space group. Tb(1) is bonded in a 10-coordinate geometry to two equivalent Ge(1), two equivalent Ge(3), and six equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(3) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Ge(2) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Ge(2) atoms. In the third Ge site, Ge(2) is bonded in a 8-coordinate geometry to six equivalent Tb(1), one Ge(1), and one Ge(3) atom. is represented by the CIF card [CIF]
