The material structure described by Pr3Sc is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded to eight equivalent Pr(1) and four equivalent Sc(1) atoms to form distorted PrPr8Sc4 cuboctahedra that share corners with four equivalent Sc(1)Pr12 cuboctahedra, corners with fourteen equivalent Pr(1)Pr8Sc4 cuboctahedra, edges with six equivalent Sc(1)Pr12 cuboctahedra, edges with twelve equivalent Pr(1)Pr8Sc4 cuboctahedra, faces with four equivalent Sc(1)Pr12 cuboctahedra, and faces with sixteen equivalent Pr(1)Pr8Sc4 cuboctahedra. Sc(1) is bonded to twelve equivalent Pr(1) atoms to form ScPr12 cuboctahedra that share corners with six equivalent Sc(1)Pr12 cuboctahedra, corners with twelve equivalent Pr(1)Pr8Sc4 cuboctahedra, edges with eighteen equivalent Pr(1)Pr8Sc4 cuboctahedra, faces with eight equivalent Sc(1)Pr12 cuboctahedra, and faces with twelve equivalent Pr(1)Pr8Sc4 cuboctahedra. is represented by the CIF file [CIF]
