DyPr3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Dy(1) is bonded to twelve equivalent Pr(1) atoms to form DyPr12 cuboctahedra that share corners with six equivalent Dy(1)Pr12 cuboctahedra, corners with twelve equivalent Pr(1)Pr8Dy4 cuboctahedra, edges with eighteen equivalent Pr(1)Pr8Dy4 cuboctahedra, faces with eight equivalent Dy(1)Pr12 cuboctahedra, and faces with twelve equivalent Pr(1)Pr8Dy4 cuboctahedra. Pr(1) is bonded to four equivalent Dy(1) and eight equivalent Pr(1) atoms to form PrPr8Dy4 cuboctahedra that share corners with four equivalent Dy(1)Pr12 cuboctahedra, corners with fourteen equivalent Pr(1)Pr8Dy4 cuboctahedra, edges with six equivalent Dy(1)Pr12 cuboctahedra, edges with twelve equivalent Pr(1)Pr8Dy4 cuboctahedra, faces with four equivalent Dy(1)Pr12 cuboctahedra, and faces with sixteen equivalent Pr(1)Pr8Dy4 cuboctahedra.

There are six shorter (3.64 Å) and six longer (3.75 Å) Dy(1)-Pr(1) bond lengths. Pr(1) is bonded to four equivalent Dy(1) and eight equivalent Pr(1) atoms to form PrPr8Dy4 cuboctahedra that share corners with four equivalent Dy(1)Pr12 cuboctahedra, corners with fourteen equivalent Pr(1)Pr8Dy4 cuboctahedra, edges with six equivalent Dy(1)Pr12 cuboctahedra, edges with twelve equivalent Pr(1)Pr8Dy4 cuboctahedra, faces with four equivalent Dy(1)Pr12 cuboctahedra, and faces with sixteen equivalent Pr(1)Pr8Dy4 cuboctahedra. There are a spread of Pr(1)-Pr(1) bond distances ranging from 3.66-3.78 Å.
