Materials Data on La2SbO6 by Materials Project

Abstract

La2SbO6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of La–O bond distances ranging from 2.42–3.12 Å. Sb is bonded in an octahedral geometry to six O atoms. There are a spread of Sb–O bond distances ranging from 1.99–2.03 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted trigonal non-coplanar geometry to two equivalent La and one Sb atom. In the second O site, O is bonded in a 3-coordinate geometry to three equivalent La and one Sb atom. In the third O site, O is bonded to three equivalent La and one Sb atom to form a mixture of distorted edge and corner-sharing OLa3Sb tetrahedra.
