TbOF is Fluorite-derived structured and crystallizes in the trigonal R-3m space group. Tb(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent F(1) atoms. O(1) is bonded to four equivalent Tb(1) atoms to form OTb4 tetrahedra that share corners with six equivalent O(1)Tb4 tetrahedra, corners with ten equivalent F(1)Tb4 tetrahedra, edges with three equivalent O(1)Tb4 tetrahedra, and edges with three equivalent F(1)Tb4 tetrahedra. F(1) is bonded to four equivalent Tb(1) atoms to form FTb4 tetrahedra that share corners with six equivalent F(1)Tb4 tetrahedra, corners with ten equivalent O(1)Tb4 tetrahedra, edges with three equivalent O(1)Tb4 tetrahedra, and edges with three equivalent F(1)Tb4 tetrahedra.
TbOF is Fluorite-derived structured and crystallizes in the trigonal R-3m space group. Tb(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent F(1) atoms. There are three shorter (2.27 Å) and one longer (2.28 Å) Tb(1)-O(1) bond length. There is one shorter (2.43 Å) and three longer (2.44 Å) Tb(1)-F(1) bond lengths. O(1) is bonded to four equivalent Tb(1) atoms to form OTb4 tetrahedra that share corners with six equivalent O(1)Tb4 tetrahedra, corners with ten equivalent F(1)Tb4 tetrahedra, edges with three equivalent O(1)Tb4 tetrahedra, and edges with three equivalent F(1)Tb4 tetrahedra.
