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.
