Materials Data on Sr3ZnPtO6 by Materials Project

Abstract

Sr3PtZnO6 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 2.50–2.75 Å. Pt4+ is bonded to six equivalent O2- atoms to form PtO6 octahedra that share faces with two equivalent ZnO6 pentagonal pyramids. All Pt–O bond lengths are 2.05 Å. Zn2+ is bonded to six equivalent O2- atoms to form distorted ZnO6 pentagonal pyramids that share faces with two equivalent PtO6 octahedra. All Zn–O bond lengths are 2.23 Å. O2- is bonded to four equivalent Sr2+, one Pt4+, and one Zn2+ atom to form a mixture of distorted edge, face, and corner-sharing OSr4ZnPt octahedra. The corner-sharing octahedra tilt angles range from 0–66°.
