The material described by Tb3Pr is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to eight Tb(1,1) and four equivalent Pr(1) atoms to form TbTb8Pr4 cuboctahedra that share corners with four equivalent Pr(1)Tb12 cuboctahedra; corners with fourteen Tb(1,1)Tb8Pr4 cuboctahedra; edges with six equivalent Pr(1)Tb12 cuboctahedra; edges with twelve Tb(1,1)Tb8Pr4 cuboctahedra; faces with four equivalent Pr(1)Tb12 cuboctahedra; and faces with sixteen Tb(1,1)Tb8Pr4 cuboctahedra. In the second Tb site, Tb(1) is bonded to eight equivalent Tb(1) and four equivalent Pr(1) atoms to form TbTb8Pr4 cuboctahedra that share corners with four equivalent Pr(1)Tb12 cuboctahedra; corners with fourteen Tb(1,1)Tb8Pr4 cuboctahedra; edges with six equivalent Pr(1)Tb12 cuboctahedra; edges with twelve equivalent Tb(1)Tb8Pr4 cuboctahedra; faces with four equivalent Pr(1)Tb12 cuboctahedra; and faces with sixteen Tb(1,1)Tb8Pr4 cuboctahedra. Pr(1) is bonded to twelve Tb(1,1) atoms to form PrTb12 cuboctahedra that share corners with six equivalent Pr(1)Tb12 cuboctahedra; corners with twelve Tb(1,1)Tb8Pr4 cuboctahedra; edges with eighteen Tb(1,1)Tb8Pr4 cuboctahedra; faces with eight equivalent Pr(1)Tb12 cuboctahedra; and faces with twelve Tb(1,1)Tb8Pr4 cuboctahedra. is represented by the CIF card [CIF]
