Title: Materials Data on Sm2O3 by Materials Project

Abstract

Sm2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. The structure is three-dimensional. there are two inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing SmO6 octahedra. The corner-sharing octahedral tilt angles are 57°. All Sm–O bond lengths are 2.37 Å. In the second Sm3+ site, Sm3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing SmO6 octahedra. The corner-sharing octahedra tilt angles range from 55–57°. There are four shorter (2.34 Å) and two longer (2.43 Å) Sm–O bond lengths. O2- is bonded to four Sm3+ atoms to form a mixture of distorted edge and corner-sharing OSm4 trigonal pyramids.
