Materials Data on NdGeAu by Materials Project

NdAuGe crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Nd is bonded to six equivalent Au and six equivalent Ge atoms to form a mixture of distorted face and edge-sharing NdGe6Au6 cuboctahedra. There are three shorter (3.18 Å) and three longer (3.35 Å) Nd–Au bond lengths. There are three shorter (3.12 Å) and three longer (3.42 Å) Nd–Ge bond lengths. Au is bonded in a 9-coordinate geometry to six equivalent Nd and three equivalent Ge atoms. All Au–Ge bond lengths are 2.63 Å. Ge is bonded in a 3-coordinate geometry to six equivalent Nd and three equivalent Au atoms.

Materials Data on Nd(GeAu)2 by Materials Project

NdAu2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Nd is bonded in a 8-coordinate geometry to eight equivalent Au and eight equivalent Ge atoms. All Nd–Au bond lengths are 3.47 Å. All Nd–Ge bond lengths are 3.37 Å. Au is bonded to four equivalent Nd and four equivalent Ge atoms to form a mixture of distorted face, edge, and corner-sharing AuNd4Ge4 tetrahedra. All Au–Ge bond lengths are 2.64 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Nd, four equivalent Au, and one Ge atom. The Ge–Ge bond length is 2.48 Å.
