Title: Materials Data on SmTmO3 by Materials Project

Abstract

TmSmO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tm3+ is bonded to six O2- atoms to form corner-sharing TmO6 octahedra. The corner-sharing octahedra tilt angles range from 42–45°. There are a spread of Tm–O bond distances ranging from 2.21–2.27 Å. Sm3+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Sm–O bond distances ranging from 2.30–2.74 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Tm3+ and two equivalent Sm3+ atoms to form distorted corner-sharing OSm2Tm2 trigonal pyramids. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Tm3+ and two equivalent Sm3+ atoms.
