Materials Data on Eu2CoRuO6 by Materials Project

Abstract

Eu2RuCoO6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.37–2.74 Å. Ru4+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six equivalent CoO6 octahedra. The corner-sharing octahedra tilt angles range from 32–33°. There are a spread of Ru–O bond distances ranging from 1.99–2.01 Å. Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six equivalent RuO6 octahedra. The corner-sharing octahedra tilt angles range from 32–33°. There are two shorter (2.05 Å) and four longer (2.14 Å) Co–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Eu3+, one Ru4+, and one Co2+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Eu3+, one Ru4+, and one Co2+ atom. In the third O2- site, O2- is bonded to two equivalent Eu3+, one Ru4+, and one Co2+ atom to form distorted corner-sharing OEu2CoRu tetrahedra.
