NdCuGe2 crystallizes in the orthorhombic Cmcm space group. Nd(1) is bonded in a 14-coordinate geometry to four equivalent Cu(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), one Ge(1), and four 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 six equivalent Nd(1), one Cu(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Nd(1) and four equivalent Cu(1) atoms.
NdCuGe2 crystallizes in the orthorhombic Cmcm space group. Nd(1) is bonded in a 14-coordinate geometry to four equivalent Cu(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. All Nd(1)-Cu(1) bond lengths are 3.23 Å. There are two shorter (3.26 Å) and two longer (3.30 Å) Nd(1)-Ge(2) bond lengths. There are four shorter (3.20 Å) and two longer (3.26 Å) Nd(1)-Ge(1) bond lengths. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), one Ge(1), and four equivalent Ge(2) atoms. The Cu(1)-Ge(1) bond length is 2.36 Å. There are two shorter (2.46 Å) and two longer (2.48 Å) Cu(1)-Ge(2) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1), one Cu(1), and two equivalent Ge(1) atoms. Both Ge(1)-Ge(1) bond lengths are 2.49 Å. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Nd(1) and four equivalent Cu(1) atoms.
