Materials Data on MgSbO3 by Materials Project

Abstract

MgSbO3 is Orthorhombic Perovskite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mg is bonded to four O atoms to form distorted MgO4 trigonal pyramids that share corners with eight SbO6 octahedra and corners with two equivalent MgO4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 54–88°. There are a spread of Mg–O bond distances ranging from 2.03–2.14 Å. There are two inequivalent Sb sites. In the first Sb site, Sb is bonded to six O atoms to form SbO6 octahedra that share corners with six equivalent SbO6 octahedra and corners with eight equivalent MgO4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 46–52°. There are a spread of Sb–O bond distances ranging from 2.00–2.08 Å. In the second Sb site, Sb is bonded to six O atoms to form SbO6 octahedra that share corners with six equivalent SbO6 octahedra and corners with eight equivalent MgO4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 46–52°. There are a spread of Sb–O bond distances ranging from 2.23–2.39 Å. There are three inequivalent O sites. In the first O site, O is bonded to two equivalent Mg and two Sb atoms to form distorted corner-sharing OMg2Sb2 tetrahedra. In the second O site, O is bonded in a distorted trigonal planar geometry to one Mg and two Sb atoms. In the third O site, O is bonded in a distorted trigonal planar geometry to one Mg and two Sb atoms.
