LuPr3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Lu(1) is bonded to twelve equivalent Pr(1) atoms to form LuPr12 cuboctahedra that share corners with six equivalent Lu(1)Pr12 cuboctahedra, corners with twelve equivalent Pr(1)Pr8Lu4 cuboctahedra, edges with eighteen equivalent Pr(1)Pr8Lu4 cuboctahedra, faces with eight equivalent Lu(1)Pr12 cuboctahedra, and faces with twelve equivalent Pr(1)Pr8Lu4 cuboctahedra. Pr(1) is bonded to four equivalent Lu(1) and eight equivalent Pr(1) atoms to form PrPr8Lu4 cuboctahedra that share corners with four equivalent Lu(1)Pr12 cuboctahedra, corners with fourteen equivalent Pr(1)Pr8Lu4 cuboctahedra, edges with six equivalent Lu(1)Pr12 cuboctahedra, edges with twelve equivalent Pr(1)Pr8Lu4 cuboctahedra, faces with four equivalent Lu(1)Pr12 cuboctahedra, and faces with sixteen equivalent Pr(1)Pr8Lu4 cuboctahedra.

There are six shorter (3.61 Å) and six longer (3.73 Å) Lu(1)-Pr(1) bond lengths. Pr(1) is bonded to four equivalent Lu(1) and eight equivalent Pr(1) atoms to form PrPr8Lu4 cuboctahedra that share corners with four equivalent Lu(1)Pr12 cuboctahedra, corners with fourteen equivalent Pr(1)Pr8Lu4 cuboctahedra, edges with six equivalent Lu(1)Pr12 cuboctahedra, edges with twelve equivalent Pr(1)Pr8Lu4 cuboctahedra, faces with four equivalent Lu(1)Pr12 cuboctahedra, and faces with sixteen equivalent Pr(1)Pr8Lu4 cuboctahedra. There are a spread of Pr(1)-Pr(1) bond distances ranging from 3.66-3.79 Å.
