Title: Materials Data on SrLa4TiAl4O15 by Materials Project

Abstract

SrLa4TiAl4O15 is (Cubic) Perovskite-derived structured and crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with six equivalent SrO12 cuboctahedra, corners with six LaO12 cuboctahedra, faces with two equivalent LaO12 cuboctahedra, faces with four equivalent SrO12 cuboctahedra, faces with two equivalent AlO6 octahedra, and faces with six equivalent TiO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.71–2.90 Å. There are five inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with five equivalent SrO12 cuboctahedra, corners with seven LaO12 cuboctahedra, faces with two equivalent SrO12 cuboctahedra, faces with four LaO12 cuboctahedra, faces with two equivalent TiO6 octahedra, and faces with six AlO6 octahedra. There are a spread of La–O bond distances ranging from 2.65–2.72 Å.
