The material described by PrY3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Pr(1) is bonded to twelve Y(1,1,1) atoms to form PrY12 cuboctahedra that share corners with six equivalent Pr(1)Y12 cuboctahedra; corners with twelve Y(1,1)Pr4Y8 cuboctahedra; edges with eighteen Y(1,1,1)Pr4Y8 cuboctahedra; faces with eight equivalent Pr(1)Y12 cuboctahedra; and faces with twelve Y(1,1,1)Pr4Y8 cuboctahedra.
