Materials Data on ZnGeO3 by Materials Project

ZnGeO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Zn2+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are three shorter (2.02 Å) and three longer (2.34 Å) Zn–O bond lengths. Ge4+ is bonded to six equivalent O2- atoms to form edge-sharing GeO6 octahedra. There is three shorter (1.90 Å) and three longer (1.96 Å) Ge–O bond length. O2- is bonded in a distorted see-saw-like geometry to two equivalent Zn2+ and two equivalent Ge4+ atoms.

Materials Data on ZnGeO3 by Materials Project

ZnGeO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Zn2+ is bonded to twelve equivalent O2- atoms to form ZnO12 cuboctahedra that share corners with twelve equivalent ZnO12 cuboctahedra, faces with six equivalent ZnO12 cuboctahedra, and faces with eight equivalent GeO6 octahedra. All Zn–O bond lengths are 2.63 Å. Ge4+ is bonded to six equivalent O2- atoms to form GeO6 octahedra that share corners with six equivalent GeO6 octahedra and faces with eight equivalent ZnO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ge–O bond lengths are 1.86 Å. O2- is bonded in a distorted linear geometry to four equivalent Zn2+ and two equivalent Ge4+ atoms.
