The structure described by Nd2CuGe6 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(4), two equivalent Ge(5), and four equivalent Ge(3) atoms. In the second Nd site, Nd(2) is bonded in a 14-coordinate geometry to four equivalent Cu(1), two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(6), and four equivalent Ge(4) atoms. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Nd(2), one Ge(4), two equivalent Ge(1), and two equivalent Ge(6) atoms. There are six inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Nd(2), two equivalent Cu(1), one Ge(2), and four equivalent Ge(6) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to two equivalent Nd(1), one Ge(1), and four equivalent Ge(5) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), and two equivalent Ge(4) atoms. In the fourth Ge site, Ge(4) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Cu(1), and two equivalent Ge(3) atoms. In the fifth Ge site, Ge(5) is bonded in a 7-coordinate geometry to two equivalent Nd(1), one Ge(6), and four equivalent Ge(2) atoms. In the sixth Ge site, Ge(6) is bonded in a 9-coordinate geometry to two equivalent Nd(2), two equivalent Cu(1), one Ge(5), and four equivalent Ge(1) atoms. is represented by the CIF card [CIF]
