Title: Materials Data on Sr4La2Mg(RuO6)2 by Materials Project

Abstract

Sr4MgLa2(RuO6)2 is (La,Ba)CuO4-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.34–2.83 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 2.43–2.84 Å. In the third 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 2.43–2.85 Å. In the fourth 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 2.43–2.86 Å. Mg2+ is bonded to six O2- atoms to form corner-sharing MgO6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Mg–O bond distances ranging from 1.97–2.27 Å. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.32–3.06 Å.

In the third O2- site, O2- is bonded in a 6-coordinate geometry to one Mg2+ and five equivalent La3+ atoms. In the fourth O2- site, O2- is bonded to four Sr2+ and two equivalent Ru4+ atoms to form a mixture of distorted corner, edge, and face-sharing OSr4Ru2 octahedra. The corner-sharing octahedra tilt angles range from 1–56°. In the fifth O2- site, O2- is bonded to four equivalent Sr2+, one La3+, and one Ru4+ atom to form distorted OSr4LaRu octahedra that share corners with seventeen OLa4Mg2 octahedra, edges with four equivalent OSr4LaRu octahedra, and faces with four equivalent OSr4Ru2 octahedra. The corner-sharing octahedra tilt angles range from 0–55°. In the sixth O2- site, O2- is bonded to four Sr2+ and two equivalent Ru4+ atoms to form distorted OSr4Ru2 octahedra that share corners with fourteen OSr5Ru octahedra, edges with two equivalent OSr4Ru2 octahedra, and faces with eight OSr5Ru octahedra. The corner-sharing octahedra tilt angles range from 0–57°. In the seventh O2- site, O2- is bonded to five Sr2+ and one Ru4+ atom to form distorted OSr5Ru octahedra that share corners with seventeen OSr4Ru2 octahedra, edges with eight OSr5Ru octahedra, and faces with four equivalent OSr4Ru2 octahedra. The corner-sharing octahedra tilt angles range from 0–57°. In the eighth O2- site, O2- is bonded to five equivalent Sr2+ and one Ru4+ atom to form distorted OSr5Ru octahedra that share corners with seventeen OSr5Ru octahedra, edges with eight equivalent OSr5Ru octahedra, and faces with four equivalent OSr4Ru2 octahedra. The corner-sharing octahedra tilt angles range from 0–57°. In the ninth O2- site, O2- is bonded to five Sr2+ and one Ru4+ atom to form distorted OSr5Ru octahedra that share corners with seventeen OSr4Ru2 octahedra, edges with eight OSr5Ru octahedra, and faces with four equivalent OSr4Ru2 octahedra.
