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.
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.
