Ce5NiGe2 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 5-coordinate geometry to two equivalent Ni(1) and three equivalent Ge(1) atoms. In the second Ce site, Ce(2) is bonded to four equivalent Ge(1) atoms to form distorted edge-sharing CeGe4 tetrahedra. Ni(1) is bonded in a 8-coordinate geometry to eight equivalent Ce(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to two equivalent Ce(2) and six equivalent Ce(1) atoms.
Ce5NiGe2 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 5-coordinate geometry to two equivalent Ni(1) and three equivalent Ge(1) atoms. There is one shorter (2.98 Å) and one longer (3.03 Å) Ce(1)-Ni(1) bond length. There are a spread of Ce(1)-Ge(1) bond distances ranging from 3.04-3.16 Å. In the second Ce site, Ce(2) is bonded to four equivalent Ge(1) atoms to form distorted edge-sharing CeGe4 tetrahedra. All Ce(2)-Ge(1) bond lengths are 3.05 Å. Ni(1) is bonded in a 8-coordinate geometry to eight equivalent Ce(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to two equivalent Ce(2) and six equivalent Ce(1) atoms.
