Materials Data on Sr3EuRhO6 by Materials Project

Abstract

Sr3EuRhO6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are a spread of Sr–O bond distances ranging from 2.59–2.78 Å. Eu3+ is bonded to six equivalent O2- atoms to form distorted EuO6 pentagonal pyramids that share faces with two equivalent RhO6 octahedra. All Eu–O bond lengths are 2.38 Å. Rh3+ is bonded to six equivalent O2- atoms to form RhO6 octahedra that share faces with two equivalent EuO6 pentagonal pyramids. All Rh–O bond lengths are 2.10 Å. O2- is bonded to four equivalent Sr2+, one Eu3+, and one Rh3+ atom to form a mixture of distorted edge, corner, and face-sharing OSr4EuRh octahedra. The corner-sharing octahedra tilt angles range from 0–64°.
