HfO2(Ge) crystallizes in the tetragonal I4_1/a space group. Hf(1) is bonded to six equivalent O(1) atoms to form distorted edge-sharing HfO6 octahedra. Ge(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a 5-coordinate geometry to three equivalent Hf(1) and two equivalent Ge(1) atoms.
HfO2(Ge) crystallizes in the tetragonal I4_1/a space group. Hf(1) is bonded to six equivalent O(1) atoms to form distorted edge-sharing HfO6 octahedra. There are a spread of Hf(1)-O(1) bond distances ranging from 2.14-2.26 Å. Ge(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. There are two shorter (2.48 Å) and two longer (2.58 Å) Ge(1)-O(1) bond lengths. O(1) is bonded in a 5-coordinate geometry to three equivalent Hf(1) and two equivalent Ge(1) atoms.
