NdGe crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Nd is bonded in a 5-coordinate geometry to seven equivalent Ge atoms. There are a spread of Nd–Ge bond distances ranging from 3.10–3.32 Å. Ge is bonded in a 9-coordinate geometry to seven equivalent Nd and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.72 Å.
Nd4LiGe4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li is bonded in a T-shaped geometry to three Ge atoms. There are a spread of Li–Ge bond distances ranging from 2.79–2.97 Å. There are two inequivalent Nd sites. In the first Nd site, Nd is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Nd–Ge bond distances ranging from 3.08–3.63 Å. In the second Nd site, Nd is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Nd–Ge bond distances ranging from 2.97–3.13 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Li, six Nd, and one Ge atom. The Ge–Ge bond length is 2.57 Å.
