Materials Data on Sr2La2Mg(RuO4)3 by Materials Project
Abstract
Sr2MgLa2(RuO4)3 is Orthorhombic Perovskite-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 12-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.49–3.05 Å. In the second Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.47–3.08 Å. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six RuO6 octahedra. The corner-sharing octahedra tilt angles range from 18–28°. There are a spread of Mg–O bond distances ranging from 2.05–2.09 Å. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of La–O bond distances ranging from 2.41–2.59 Å. In the second La3+ site, La3+ is bonded in a 9-coordinate geometry to six O2- atoms. There are a spread of La–O bond distances ranging from 2.41–2.62 Å. There are three inequivalent Ru4+ sites. In the first Ru4+ site, Ru4+ is bonded to six O2- atoms to form corner-sharingmore »
