Materials Data on HoGeO3 by Materials Project
HoGeO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ho3+ is bonded to twelve equivalent O2- atoms to form HoO12 cuboctahedra that share corners with twelve equivalent HoO12 cuboctahedra, faces with six equivalent HoO12 cuboctahedra, and faces with eight equivalent GeO6 octahedra. All Ho–O bond lengths are 2.76 Å. Ge3+ is bonded to six equivalent O2- atoms to form GeO6 octahedra that share corners with six equivalent GeO6 octahedra and faces with eight equivalent HoO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ge–O bond lengths are 1.95 Å. O2- is bonded in a distorted linear geometry to four equivalent Ho3+ and two equivalent Ge3+ atoms.
