Pr3Ag is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to four equivalent Pr(1), four equivalent Pr(2), and four equivalent Ag(1) atoms to form distorted PrPr8Ag4 cuboctahedra that share corners with twelve equivalent Pr(1)Pr8Ag4 cuboctahedra, edges with eight equivalent Pr(1)Pr8Ag4 cuboctahedra, edges with eight equivalent Ag(1)Pr12 cuboctahedra, faces with four equivalent Ag(1)Pr12 cuboctahedra, and faces with ten equivalent Pr(1)Pr8Ag4 cuboctahedra. In the second Pr site, Pr(2) is bonded in a square co-planar geometry to eight equivalent Pr(1) and four equivalent Ag(1) atoms. Ag(1) is bonded to four equivalent Pr(2) and eight equivalent Pr(1) atoms to form AgPr12 cuboctahedra that share corners with four equivalent Ag(1)Pr12 cuboctahedra, edges with eight equivalent Ag(1)Pr12 cuboctahedra, edges with sixteen equivalent Pr(1)Pr8Ag4 cuboctahedra, faces with four equivalent Ag(1)Pr12 cuboctahedra, and faces with eight equivalent Pr(1)Pr8Ag4 cuboctahedra.
