Materials Data on ScCrO3 by Materials Project
ScCrO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sc3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Sc–O bond distances ranging from 2.09–2.37 Å. Cr3+ is bonded to six O2- atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedra tilt angles range from 42–46°. There are a spread of Cr–O bond distances ranging from 1.99–2.05 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sc3+ and two equivalent Cr3+ atoms. In the second O2- site, O2- is bonded to two equivalent Sc3+ and two equivalent Cr3+ atoms to form distorted corner-sharing OSc2Cr2 trigonal pyramids.
