NdAlGe crystallizes in the tetragonal I4_1md space group. There are four inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to six Al(1,1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing NdAl6Ge6 cuboctahedra. In the second Nd site, Nd(1) is bonded to six Al(1,1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing NdAl6Ge6 cuboctahedra. In the third Nd site, Nd(1) is bonded to six Al(1,1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing NdAl6Ge6 cuboctahedra. In the fourth Nd site, Nd(1) is bonded to six Al(1,1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing NdAl6Ge6 cuboctahedra. There are three inequivalent Al sites. In the first Al site, Al(1) is bonded in a distorted trigonal planar geometry to six Nd(1,1) and three equivalent Ge(1) atoms. In the second Al site, Al(1) is bonded in a distorted trigonal planar geometry to six Nd(1,1) and three equivalent Ge(1) atoms. In the third Al site, Al(1) is bonded in a distorted trigonal planar geometry to six Nd(1,1) and three equivalent Ge(1) atoms. Ge(1) is bonded in a distorted trigonal planar geometry to six Nd(1,1) and three Al(1,1) atoms.

In the first Nd site, Nd(1) is bonded to six Al(1,1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing NdAl6Ge6 cuboctahedra. There are two shorter (3.24 Å) and four longer (3.26 Å) Nd(1)-Al(1,1) bond lengths. There are four shorter (3.25 Å) and two longer (3.26 Å) Nd(1)-Ge(1) bond lengths.
