Materials Data on LaPtO3 by Materials Project

Abstract

LaPtO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. La2+ is bonded to twelve equivalent O2- atoms to form LaO12 cuboctahedra that share corners with twelve equivalent LaO12 cuboctahedra, faces with six equivalent LaO12 cuboctahedra, and faces with eight equivalent PtO6 octahedra. All La–O bond lengths are 2.89 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 LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Pt–O bond lengths are 2.04 Å. O2- is bonded to four equivalent La2+ and two equivalent Pt4+ atoms to form a mixture of distorted corner, edge, and face-sharing OLa4Pt2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
