The compound described by Ce3NiGe2 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 6-coordinate geometry to one Ni(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. In the second Ce site, Ce(2) is bonded in a 7-coordinate geometry to two equivalent Ni(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. In the third Ce site, Ce(3) is bonded in a 8-coordinate geometry to three equivalent Ni(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Ni(1) is bonded in a 9-coordinate geometry to one Ce(1), two equivalent Ce(2), three equivalent Ce(3), one Ge(1), and two 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 Ce(3), three equivalent Ce(1), three equivalent Ce(2), and one Ni(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), three equivalent Ce(3), and two equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
