Materials Data on Sr4PtO6 by Materials Project

Sr4PtO6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are a spread of Sr–O bond distances ranging from 2.63–2.80 Å. In the second Sr2+ site, Sr2+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Sr–O bond lengths are 2.48 Å. Pt4+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Pt–O bond lengths are 2.09 Å. O2- is bonded to five Sr2+ and one Pt4+ atom to form a mixture of distorted corner, edge, and face-sharing OSr5Pt octahedra. The corner-sharing octahedra tilt angles range from 0–64°.

SrPtO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sr2+ is bonded to twelve equivalent O2- atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, and faces with eight equivalent PtO6 octahedra. All Sr–O bond lengths are 2.87 Å. Pt4+ is bonded to six equivalent O2- atoms to form PtO6 octahedra that share corners with six equivalent PtO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Pt–O bond lengths are 2.03 Å. O2- is bonded to four equivalent Sr2+ and two equivalent Pt4+ atoms to form a mixture of distorted corner, edge, and face-sharing OSr4Pt2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
