NdAg is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Nd is bonded in a body-centered cubic geometry to eight equivalent Ag atoms. All Nd–Ag bond lengths are 3.26 Å. Ag is bonded in a body-centered cubic geometry to eight equivalent Nd atoms.
Ag2Nd crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Nd is bonded to twelve equivalent Ag atoms to form a mixture of face and edge-sharing NdAg12 cuboctahedra. There are eight shorter (3.31 Å) and four longer (3.32 Å) Nd–Ag bond lengths. Ag is bonded in a 9-coordinate geometry to six equivalent Nd and three equivalent Ag atoms. All Ag–Ag bond lengths are 2.79 Å.
Nd3Ag crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Nd is bonded in a 4-coordinate geometry to four equivalent Ag atoms. There are two shorter (3.34 Å) and two longer (3.56 Å) Nd–Ag bond lengths. Ag is bonded to twelve equivalent Nd atoms to form a mixture of face and corner-sharing AgNd12 cuboctahedra.
Ag2Nd crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Nd is bonded in a 12-coordinate geometry to twelve equivalent Ag atoms. There are a spread of Nd–Ag bond distances ranging from 3.25–3.44 Å. Ag is bonded in a 10-coordinate geometry to six equivalent Nd and four equivalent Ag atoms. There are a spread of Ag–Ag bond distances ranging from 2.78–3.08 Å.
