Materials Data on CaSbO3 by Materials Project

Abstract

CaSbO3 is Orthorhombic Perovskite structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Ca sites. In the first Ca site, Ca is bonded in a 4-coordinate geometry to eight O atoms. There are a spread of Ca–O bond distances ranging from 2.37–2.91 Å. In the second Ca site, Ca is bonded in a 4-coordinate geometry to eight O atoms. There are a spread of Ca–O bond distances ranging from 2.29–2.87 Å. There are two inequivalent Sb sites. In the first Sb site, Sb is bonded to six O atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 35–41°. There are a spread of Sb–O bond distances ranging from 2.18–2.32 Å. In the second Sb site, Sb is bonded to six O atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 35–39°. There are four shorter (2.02 Å) and two longer (2.16 Å) Sb–O bond lengths. There are four inequivalent O sites. In the first O site, O is bonded in a 5-coordinate geometry to three Ca and two Sb atoms. In the second O site, O is bonded in a 5-coordinate geometry to three Ca and two Sb atoms. In the third O site, O is bonded to two Ca and two equivalent Sb atoms to form distorted corner-sharing OCa2Sb2 tetrahedra. In the fourth O site, O is bonded to two Ca and two equivalent Sb atoms to form distorted corner-sharing OCa2Sb2 trigonal pyramids.
