In the second Nd site, Nd(2) is bonded in a 7-coordinate geometry to two equivalent Co(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the third Nd site, Nd(3) is bonded in a 8-coordinate geometry to three equivalent Co(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. Co(1) is bonded in a 9-coordinate geometry to one Nd(1), two equivalent Nd(2), three equivalent Nd(3), 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 Nd(1), two equivalent Nd(2), three equivalent Nd(3), and two equivalent Co(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Nd(3), three equivalent Nd(1), three equivalent Nd(2), and one Co(1) atom.
