Materials Data on Eu3RuO7 by Materials Project
Abstract
Eu3RuO7 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Eu3+ sites. In the first Eu3+ site, Eu3+ is bonded to seven O2- atoms to form distorted EuO7 pentagonal bipyramids that share corners with two equivalent RuO6 octahedra, corners with three equivalent EuO7 pentagonal bipyramids, edges with two equivalent RuO6 octahedra, and edges with two equivalent EuO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 36°. There are a spread of Eu–O bond distances ranging from 2.26–2.62 Å. In the second Eu3+ site, Eu3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.39 Å) and four longer (2.74 Å) Eu–O bond lengths. Ru5+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with two equivalent RuO6 octahedra, corners with four equivalent EuO7 pentagonal bipyramids, and edges with four equivalent EuO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 36°. There is four shorter (1.94 Å) and two longer (1.99 Å) Ru–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Eu3+ and two equivalent Ru5+ atoms. In the secondmore »
