The compound described by Tb2CoGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 8-coordinate geometry to two equivalent Co(1), one Ge(2), and five equivalent Ge(1) atoms. In the second Tb site, Tb(2) is bonded in a 11-coordinate geometry to four equivalent Co(1), two equivalent Ge(1), and five equivalent Ge(2) atoms. Co(1) is bonded in a 10-coordinate geometry to two equivalent Tb(1), four equivalent Tb(2), one Ge(1), and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Tb(2), five equivalent Tb(1), one Co(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to one Tb(1), five equivalent Tb(2), three equivalent Co(1), and one Ge(2) atom. is represented by the CIF file [CIF]
