Materials Data on SrTb by Materials Project
SrTb crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Sr is bonded to six equivalent Sr and six equivalent Tb atoms to form SrSr6Tb6 cuboctahedra that share corners with eighteen equivalent SrSr6Tb6 cuboctahedra, edges with six equivalent SrSr6Tb6 cuboctahedra, edges with twelve equivalent TbSr6Tb6 cuboctahedra, faces with eight equivalent SrSr6Tb6 cuboctahedra, and faces with twelve equivalent TbSr6Tb6 cuboctahedra. All Sr–Sr bond lengths are 3.82 Å. All Sr–Tb bond lengths are 3.87 Å.
