The compound described by TbY3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Tb(1) is bonded to twelve equivalent Y(1) atoms to form TbY12 cuboctahedra that share corners with twelve equivalent Tb(1)Y12 cuboctahedra, edges with twenty-four equivalent Y(1)Tb4Y8 cuboctahedra, faces with six equivalent Tb(1)Y12 cuboctahedra, and faces with twelve equivalent Y(1)Tb4Y8 cuboctahedra. Y(1) is bonded to four equivalent Tb(1) and eight equivalent Y(1) atoms to form YTb4Y8 cuboctahedra that share corners with twelve equivalent Y(1)Tb4Y8 cuboctahedra, edges with eight equivalent Tb(1)Y12 cuboctahedra, edges with sixteen equivalent Y(1)Tb4Y8 cuboctahedra, faces with four equivalent Tb(1)Y12 cuboctahedra, and faces with fourteen equivalent Y(1)Tb4Y8 cuboctahedra. is represented by the CIF file [CIF]
