Materials Data on YbGaO3 by Materials Project

YbGaO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Yb3+ is bonded to twelve equivalent O2- atoms to form YbO12 cuboctahedra that share corners with twelve equivalent YbO12 cuboctahedra, faces with six equivalent YbO12 cuboctahedra, and faces with eight equivalent GaO6 octahedra. All Yb–O bond lengths are 2.71 Å. Ga3+ is bonded to six equivalent O2- atoms to form GaO6 octahedra that share corners with six equivalent GaO6 octahedra and faces with eight equivalent YbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ga–O bond lengths are 1.92 Å. O2- is bonded in a distorted linear geometry to four equivalent Yb3+ and two equivalent Ga3+ atoms.

Materials Data on YbGaO3 by Materials Project

YbGaO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Yb3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Yb–O bond distances ranging from 2.31–2.62 Å. Ga3+ is bonded to six O2- atoms to form corner-sharing GaO6 octahedra. The corner-sharing octahedra tilt angles range from 30–34°. There are a spread of Ga–O bond distances ranging from 1.94–2.02 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Yb3+ and two equivalent Ga3+ atoms. In the second O2- site, O2- is bonded to two equivalent Yb3+ and two equivalent Ga3+ atoms to form distorted corner-sharing OYb2Ga2 tetrahedra.
