Materials Data on InRhO3 by Materials Project

RhInO3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rh3+ is bonded in a distorted rectangular see-saw-like geometry to six O2- atoms. There are a spread of Rh–O bond distances ranging from 2.01–2.59 Å. In3+ is bonded to six O2- atoms to form corner-sharing InO6 octahedra. The corner-sharing octahedra tilt angles range from 54–56°. There are a spread of In–O bond distances ranging from 2.15–2.34 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Rh3+ and two equivalent In3+ atoms. In the second O2- site, O2- is bonded in a distorted see-saw-like geometry to two equivalent Rh3+ and two equivalent In3+ atoms.

Materials Data on InRhO3 by Materials Project

RhInO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rh3+ is bonded to six O2- atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedra tilt angles range from 42–45°. There are four shorter (2.05 Å) and two longer (2.13 Å) Rh–O bond lengths. In3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of In–O bond distances ranging from 2.18–2.40 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Rh3+ and two equivalent In3+ atoms to form a mixture of distorted edge and corner-sharing OIn2Rh2 trigonal pyramids. In the second O2- site, O2- is bonded to two equivalent Rh3+ and two equivalent In3+ atoms to form a mixture of distorted edge and corner-sharing OIn2Rh2 trigonal pyramids.
