The material structure described by TbO2HfO12 crystallizes in the cubic Fd-3m space group. The structure consists of one HfO12 framework and one TbO2 framework. In the HfO12 framework, Hf(1) is bonded in a 12-coordinate geometry to twelve equivalent O(2) atoms. O(2) is bonded in a 4-coordinate geometry to one Hf(1) and three equivalent O(2) atoms. In the TbO2 framework, Tb(1) is bonded to four equivalent O(1) atoms to form corner-sharing TbO4 tetrahedra. O(1) is bonded in a linear geometry to two equivalent Tb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
