Tb3Ru2Ge3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 10-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and five equivalent Ge(1) atoms. In the second Tb site, Tb(2) is bonded in a 9-coordinate geometry to four equivalent Ru(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Ru(1) is bonded in a 10-coordinate geometry to two equivalent Tb(2), four equivalent Tb(1), 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(2), five equivalent Tb(1), three equivalent Ru(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Tb(2), four equivalent Tb(1), and two equivalent Ru(1) atoms.
