Materials Data on Sr3NiPtO6 by Materials Project
Sr3NiPtO6 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 2.49–2.78 Å. Pt4+ is bonded to six equivalent O2- atoms to form PtO6 octahedra that share faces with two equivalent NiO6 pentagonal pyramids. All Pt–O bond lengths are 2.05 Å. Ni2+ is bonded to six equivalent O2- atoms to form distorted NiO6 pentagonal pyramids that share faces with two equivalent PtO6 octahedra. All Ni–O bond lengths are 2.20 Å. O2- is bonded to four equivalent Sr2+, one Pt4+, and one Ni2+ atom to form a mixture of distorted corner, edge, and face-sharing OSr4NiPt octahedra. The corner-sharing octahedra tilt angles range from 0–67°.
