Materials Data on YbCrO3 by Materials Project

YbCrO3 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 2.29–2.59 Å. Cr3+ is bonded to six O2- atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles are 28°. There are a spread of Cr–O bond distances ranging from 1.91–1.99 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 Cr3+ atoms. In the second O2- site, O2- is bonded to two equivalent Yb3+ and two equivalent Cr3+ atoms to form distorted corner-sharing OYb2Cr2 tetrahedra.

Materials Data on YbCrO3 by Materials Project

YbCrO3 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 CrO6 octahedra. All Yb–O bond lengths are 2.67 Å. Cr3+ is bonded to six equivalent O2- atoms to form CrO6 octahedra that share corners with six equivalent CrO6 octahedra and faces with eight equivalent YbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cr–O bond lengths are 1.89 Å. O2- is bonded in a distorted linear geometry to four equivalent Yb3+ and two equivalent Cr3+ atoms.
