The material structure described by RbPr3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Rb(1) is bonded to four equivalent Pr(2) and eight equivalent Pr(1) atoms to form RbPr12 cuboctahedra that share corners with four equivalent Rb(1)Pr12 cuboctahedra, corners with eight equivalent Pr(2)Rb4Pr8 cuboctahedra, edges with eight equivalent Rb(1)Pr12 cuboctahedra, edges with sixteen equivalent Pr(1)Rb4Pr8 cuboctahedra, faces with four equivalent Rb(1)Pr12 cuboctahedra, faces with six equivalent Pr(2)Rb4Pr8 cuboctahedra, and faces with eight equivalent Pr(1)Rb4Pr8 cuboctahedra. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to four equivalent Rb(1), four equivalent Pr(1), and four equivalent Pr(2) atoms to form PrRb4Pr8 cuboctahedra that share corners with twelve equivalent Pr(1)Rb4Pr8 cuboctahedra, edges with eight equivalent Rb(1)Pr12 cuboctahedra, edges with eight equivalent Pr(1)Rb4Pr8 cuboctahedra, edges with eight equivalent Pr(2)Rb4Pr8 cuboctahedra, faces with four equivalent Rb(1)Pr12 cuboctahedra, faces with four equivalent Pr(2)Rb4Pr8 cuboctahedra, and faces with ten equivalent Pr(1)Rb4Pr8 cuboctahedra. In the second Pr site, Pr(2) is bonded to four equivalent Rb(1) and eight equivalent Pr(1) atoms to form PrRb4Pr8 cuboctahedra that share corners with four equivalent Pr(2)Rb4Pr8 cuboctahedra, corners with eight equivalent Rb(1)Pr12 cuboctahedra, edges with eight equivalent Pr(2)Rb4Pr8 cuboctahedra, edges with sixteen equivalent Pr(1)Rb4Pr8 cuboctahedra, faces with four equivalent Pr(2)Rb4Pr8 cuboctahedra, faces with six equivalent Rb(1)Pr12 cuboctahedra, and faces with eight equivalent Pr(1)Rb4Pr8 cuboctahedra. is represented by the CIF file [CIF]
