Materials Data on BaPtO3 by Materials Project
Abstract
BaPtO3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are four inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with six BaO12 cuboctahedra, and faces with eight PtO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.79–3.25 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, corners with six PtO6 octahedra, faces with eight BaO12 cuboctahedra, and faces with six PtO6 octahedra. The corner-sharing octahedra tilt angles range from 9–12°. There are a spread of Ba–O bond distances ranging from 2.94–3.29 Å. In the third Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, and faces with eight PtO6 octahedra. There are six shorter (2.82 Å) and six longer (2.94 Å) Ba–O bond lengths. In the fourth Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with nine BaO12 cuboctahedra, corners withmore »

The corner-sharing octahedral tilt angles are 17°. There are three shorter (2.04 Å) and three longer (2.08 Å) Pt–O bond lengths.
