Materials Data on Sr3ZnRhO6 by Materials Project

Abstract

Sr3ZnRhO6 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 2.50–2.73 Å. Rh4+ is bonded to six equivalent O2- atoms to form RhO6 octahedra that share faces with two equivalent ZnO6 pentagonal pyramids. All Rh–O bond lengths are 2.04 Å. Zn2+ is bonded to six equivalent O2- atoms to form distorted ZnO6 pentagonal pyramids that share faces with two equivalent RhO6 octahedra. All Zn–O bond lengths are 2.22 Å. O2- is bonded to four equivalent Sr2+, one Rh4+, and one Zn2+ atom to form a mixture of distorted corner, edge, and face-sharing OSr4ZnRh octahedra. The corner-sharing octahedra tilt angles range from 0–65°.
