Title: Materials Data on Sr2LaTa3O11 by Materials Project

Abstract

Sr2LaTa3O11 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Sr2+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are four shorter (2.51 Å) and two longer (2.59 Å) Sr–O bond lengths. La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with two equivalent LaO12 cuboctahedra, faces with two equivalent LaO12 cuboctahedra, and faces with eight TaO6 octahedra. There are a spread of La–O bond distances ranging from 2.62–2.88 Å. There are two inequivalent Ta5+ sites. In the first Ta5+ site, Ta5+ is bonded to six O2- atoms to form TaO6 octahedra that share corners with four TaO6 octahedra and faces with two equivalent LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 10–19°. There are a spread of Ta–O bond distances ranging from 1.89–2.14 Å. In the second Ta5+ site, Ta5+ is bonded to six O2- atoms to form TaO6 octahedra that share corners with six TaO6 octahedra and faces with four equivalent LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–10°. There is two shorter (1.99 Å) and four longer (2.00 Å) Ta–O bond length. There are four inequivalent O2- sites.
