YbPr3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Yb(1) is bonded to twelve Pr(1,1,1) atoms to form YbPr12 cuboctahedra that share corners with six equivalent Yb(1)Pr12 cuboctahedra; corners with twelve Pr(1,1)Yb4Pr8 cuboctahedra; edges with eighteen Pr(1,1,1)Yb4Pr8 cuboctahedra; faces with eight equivalent Yb(1)Pr12 cuboctahedra; and faces with twelve Pr(1,1,1)Yb4Pr8 cuboctahedra. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to four equivalent Yb(1) and eight Pr(1,1,1) atoms to form PrYb4Pr8 cuboctahedra that share corners with four equivalent Yb(1)Pr12 cuboctahedra; corners with fourteen Pr(1,1)Yb4Pr8 cuboctahedra; edges with six equivalent Yb(1)Pr12 cuboctahedra; edges with twelve Pr(1,1,1)Yb4Pr8 cuboctahedra; faces with four equivalent Yb(1)Pr12 cuboctahedra; and faces with sixteen Pr(1,1,1)Yb4Pr8 cuboctahedra. In the second Pr site, Pr(1) is bonded to four equivalent Yb(1) and eight equivalent Pr(1) atoms to form PrYb4Pr8 cuboctahedra that share corners with four equivalent Yb(1)Pr12 cuboctahedra; corners with fourteen Pr(1,1)Yb4Pr8 cuboctahedra; edges with six equivalent Yb(1)Pr12 cuboctahedra; edges with twelve equivalent Pr(1)Yb4Pr8 cuboctahedra; faces with four equivalent Yb(1)Pr12 cuboctahedra; and faces with sixteen Pr(1,1,1)Yb4Pr8 cuboctahedra.

There are six shorter (3.72 Å) and six longer (3.74 Å) Yb(1)-Pr(1,1,1) bond lengths. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to four equivalent Yb(1) and eight Pr(1,1,1) atoms to form PrYb4Pr8 cuboctahedra that share corners with four equivalent Yb(1)Pr12 cuboctahedra; corners with fourteen Pr(1,1)Yb4Pr8 cuboctahedra; edges with six equivalent Yb(1)Pr12 cuboctahedra; edges with twelve Pr(1,1,1)Yb4Pr8 cuboctahedra; faces with four equivalent Yb(1)Pr12 cuboctahedra; and faces with sixteen Pr(1,1,1)Yb4Pr8 cuboctahedra. There are a spread of Pr(1)-Pr(1,1,1) bond distances ranging from 3.70-3.78 Å. In the second Pr site, Pr(1) is bonded to four equivalent Yb(1) and eight equivalent Pr(1) atoms to form PrYb4Pr8 cuboctahedra that share corners with four equivalent Yb(1)Pr12 cuboctahedra; corners with fourteen Pr(1,1)Yb4Pr8 cuboctahedra; edges with six equivalent Yb(1)Pr12 cuboctahedra; edges with twelve equivalent Pr(1)Yb4Pr8 cuboctahedra; faces with four equivalent Yb(1)Pr12 cuboctahedra; and faces with sixteen Pr(1,1,1)Yb4Pr8 cuboctahedra.
