The material described by Ce2NiGe3 is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. Ce(1) is bonded to three equivalent Ni(1), three equivalent Ge(1), three equivalent Ge(2), and three equivalent Ge(3) atoms to form a mixture of face and edge-sharing CeNi3Ge9 cuboctahedra. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent Ni(1) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to six equivalent Ce(1) and three equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
