Title: Materials Data on Ca2LaRuO6 by Materials Project

Abstract

Ca2LaRuO6 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.36–2.95 Å. In the second Ca2+ site, Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share corners with six equivalent RuO6 octahedra. The corner-sharing octahedra tilt angles range from 33–39°. There are a spread of Ca–O bond distances ranging from 2.27–2.33 Å. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.38–2.96 Å. Ru5+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six equivalent CaO6 octahedra. The corner-sharing octahedra tilt angles range from 33–39°. There are a spread of Ru–O bond distances ranging from 1.98–2.00 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to two Ca2+, two equivalent La3+, and one Ru5+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three Ca2+, one La3+, and one Ru5+more » atom. In the third O2- site, O2- is bonded to two Ca2+, one La3+, and one Ru5+ atom to form distorted corner-sharing OCa2LaRu tetrahedra. In the fourth O2- site, O2- is bonded to two Ca2+, one La3+, and one Ru5+ atom to form distorted corner-sharing OCa2LaRu tetrahedra. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to three Ca2+, one La3+, and one Ru5+ atom. In the sixth O2- site, O2- is bonded in a 5-coordinate geometry to two Ca2+, two equivalent La3+, and one Ru5+ atom.« less
