Nd3(RuGe)2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 9-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. In the second Nd site, Nd(2) is bonded in a 9-coordinate geometry to four equivalent Ru(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Ru(1) is bonded in a 9-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), one Ge(2), and two equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to two equivalent Nd(2), six equivalent Nd(1), and four equivalent Ru(1) atoms to form a mixture of distorted edge, corner, and face-sharing GeNd8Ru4 cuboctahedra. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Nd(2), four equivalent Nd(1), and two equivalent Ru(1) atoms.

In the first Nd site, Nd(1) is bonded in a 9-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. There are a spread of Nd(1)-Ru(1) bond distances ranging from 2.87-3.18 Å. There is one shorter (3.11 Å) and one longer (3.12 Å) Nd(1)-Ge(2) bond length. There are a spread of Nd(1)-Ge(1) bond distances ranging from 3.20-3.58 Å. In the second Nd site, Nd(2) is bonded in a 9-coordinate geometry to four equivalent Ru(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. There are two shorter (3.05 Å) and two longer (3.28 Å) Nd(2)-Ru(1) bond lengths. Both Nd(2)-Ge(1) bond lengths are 3.42 Å. There are a spread of Nd(2)-Ge(2) bond distances ranging from 3.06-3.15 Å. Ru(1) is bonded in a 9-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), one Ge(2), and two equivalent Ge(1) atoms. The Ru(1)-Ge(2) bond length is 2.60 Å.
