The compound described by Tb3NiGe2 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 8-coordinate geometry to three equivalent Ni(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. In the second Tb site, Tb(2) is bonded in a 6-coordinate geometry to one Ni(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the third Tb site, Tb(3) is bonded in a 7-coordinate geometry to two equivalent Ni(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Ni(1) is bonded in a 9-coordinate geometry to one Tb(2), two equivalent Tb(3), three equivalent Tb(1), one Ge(2), and two equivalent Ge(1) 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), two equivalent Tb(3), three equivalent Tb(1), and two equivalent Ni(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Tb(1), three equivalent Tb(2), three equivalent Tb(3), and one Ni(1) atom. is represented by the CIF card [CIF]
