The compound described by DyPr3 is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded to four equivalent Pr(2) and eight equivalent Pr(1) atoms to form DyPr12 cuboctahedra that share corners with four equivalent Dy(1)Pr12 cuboctahedra, corners with eight equivalent Pr(2)Pr8Dy4 cuboctahedra, edges with eight equivalent Dy(1)Pr12 cuboctahedra, edges with sixteen equivalent Pr(1)Pr8Dy4 cuboctahedra, faces with four equivalent Dy(1)Pr12 cuboctahedra, faces with six equivalent Pr(2)Pr8Dy4 cuboctahedra, and faces with eight equivalent Pr(1)Pr8Dy4 cuboctahedra. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to four equivalent Dy(1), four equivalent Pr(1), and four equivalent Pr(2) atoms to form PrPr8Dy4 cuboctahedra that share corners with twelve equivalent Pr(1)Pr8Dy4 cuboctahedra, edges with eight equivalent Dy(1)Pr12 cuboctahedra, edges with eight equivalent Pr(1)Pr8Dy4 cuboctahedra, edges with eight equivalent Pr(2)Pr8Dy4 cuboctahedra, faces with four equivalent Dy(1)Pr12 cuboctahedra, faces with four equivalent Pr(2)Pr8Dy4 cuboctahedra, and faces with ten equivalent Pr(1)Pr8Dy4 cuboctahedra. In the second Pr site, Pr(2) is bonded to four equivalent Dy(1) and eight equivalent Pr(1) atoms to form PrPr8Dy4 cuboctahedra that share corners with four equivalent Pr(2)Pr8Dy4 cuboctahedra, corners with eight equivalent Dy(1)Pr12 cuboctahedra, edges with eight equivalent Pr(2)Pr8Dy4 cuboctahedra, edges with sixteen equivalent Pr(1)Pr8Dy4 cuboctahedra, faces with four equivalent Pr(2)Pr8Dy4 cuboctahedra, faces with six equivalent Dy(1)Pr12 cuboctahedra, and faces with eight equivalent Pr(1)Pr8Dy4 cuboctahedra. is represented by the CIF card [CIF]
