PrAg is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pr is bonded in a body-centered cubic geometry to eight equivalent Ag atoms. All Pr–Ag bond lengths are 3.29 Å. Ag is bonded in a body-centered cubic geometry to eight equivalent Pr atoms.
Ag2Pr crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Pr is bonded to twelve equivalent Ag atoms to form a mixture of edge and face-sharing PrAg12 cuboctahedra. All Pr–Ag bond lengths are 3.33 Å. Ag is bonded in a 9-coordinate geometry to six equivalent Pr and three equivalent Ag atoms. All Ag–Ag bond lengths are 2.80 Å.
Pr3Ag is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded to eight Pr and four equivalent Ag atoms to form distorted PrPr8Ag4 cuboctahedra that share corners with twelve equivalent PrPr8Ag4 cuboctahedra, edges with eight equivalent PrPr8Ag4 cuboctahedra, edges with eight equivalent AgPr12 cuboctahedra, faces with four equivalent AgPr12 cuboctahedra, and faces with ten equivalent PrPr8Ag4 cuboctahedra. There are four shorter (3.42 Å) and four longer (3.56 Å) Pr–Pr bond lengths. All Pr–Ag bond lengths are 3.56 Å. In the second Pr site, Pr is bonded in a square co-planar geometry to eight equivalent Pr and four equivalent Ag atoms. All Pr–Ag bond lengths are 3.42 Å. Ag is bonded to twelve Pr atoms to form AgPr12 cuboctahedra that share corners with four equivalent AgPr12 cuboctahedra, edges with eight equivalent AgPr12 cuboctahedra, edges with sixteen equivalent PrPr8Ag4 cuboctahedra, faces with four equivalent AgPr12 cuboctahedra, and faces with eight equivalent PrPr8Ag4 cuboctahedra.
Ag2Pr crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to twelve equivalent Ag atoms. There are a spread of Pr–Ag bond distances ranging from 3.25–3.41 Å. Ag is bonded in a 10-coordinate geometry to six equivalent Pr and four equivalent Ag atoms.
