The compound described by Tb2RuGe2 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 Ru(1), one Ge(1), and five equivalent Ge(2) atoms. In the second Tb site, Tb(2) is bonded in a 10-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and five equivalent Ge(1) atoms. Ru(1) is bonded in a 10-coordinate geometry to two equivalent Tb(1), four equivalent Tb(2), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to one Tb(1), five equivalent Tb(2), three equivalent Ru(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Tb(2), five equivalent Tb(1), one Ru(1), and one Ge(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
