Title: Materials Data on BaEu2ZnO5 by Materials Project

Abstract

Eu2BaZnO5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ba2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.72–3.35 Å. 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 four equivalent EuO7 pentagonal bipyramids, edges with three equivalent EuO7 pentagonal bipyramids, edges with two equivalent ZnO5 trigonal bipyramids, a faceface with one EuO7 pentagonal bipyramid, and a faceface with one ZnO5 trigonal bipyramid. There are a spread of Eu–O bond distances ranging from 2.41–2.46 Å. In the second Eu3+ site, Eu3+ is bonded to seven O2- atoms to form distorted EuO7 pentagonal bipyramids that share corners with five equivalent ZnO5 trigonal bipyramids, edges with five EuO7 pentagonal bipyramids, an edgeedge with one ZnO5 trigonal bipyramid, and a faceface with one EuO7 pentagonal bipyramid. There are a spread of Eu–O bond distances ranging from 2.34–2.48 Å. Zn2+ is bonded to five O2- atoms to form ZnO5 trigonal bipyramids that share corners with five equivalent EuO7 pentagonal bipyramids, edges with three EuO7 pentagonal bipyramids, and a faceface withmore » one EuO7 pentagonal bipyramid. There are a spread of Zn–O bond distances ranging from 2.01–2.15 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Ba2+, two Eu3+, and one Zn2+ atom to form a mixture of distorted corner and edge-sharing OBa3Eu2Zn octahedra. The corner-sharing octahedral tilt angles are 3°. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, three Eu3+, and one Zn2+ atom. In the third O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Ba2+, three Eu3+, and one Zn2+ atom.« less
