Pr3Tl is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pr(1) is bonded to eight equivalent Pr(1) and four equivalent Tl(1) atoms to form distorted PrPr8Tl4 cuboctahedra that share corners with twelve equivalent Pr(1)Pr8Tl4 cuboctahedra, edges with eight equivalent Tl(1)Pr12 cuboctahedra, edges with sixteen equivalent Pr(1)Pr8Tl4 cuboctahedra, faces with four equivalent Tl(1)Pr12 cuboctahedra, and faces with fourteen equivalent Pr(1)Pr8Tl4 cuboctahedra. Tl(1) is bonded to twelve equivalent Pr(1) atoms to form TlPr12 cuboctahedra that share corners with twelve equivalent Tl(1)Pr12 cuboctahedra, edges with twenty-four equivalent Pr(1)Pr8Tl4 cuboctahedra, faces with six equivalent Tl(1)Pr12 cuboctahedra, and faces with twelve equivalent Pr(1)Pr8Tl4 cuboctahedra.
