Ba3YRuPtO9 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with nine BaO12 cuboctahedra, corners with three equivalent RuO6 octahedra, faces with seven BaO12 cuboctahedra, faces with three equivalent YO6 octahedra, and faces with four equivalent PtO6 octahedra. The corner-sharing octahedral tilt angles are 12°. There are a spread of Ba–O bond distances ranging from 2.98–3.12 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with nine BaO12 cuboctahedra, corners with three equivalent PtO6 octahedra, faces with seven BaO12 cuboctahedra, faces with three equivalent YO6 octahedra, and faces with four equivalent RuO6 octahedra. The corner-sharing octahedral tilt angles are 8°. There are a spread of Ba–O bond distances ranging from 2.89–3.23 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 BaO12 cuboctahedra, faces with two YO6 octahedra, faces with three equivalent RuO6 octahedra, and faces with three equivalent PtO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.95–3.12 Å. There are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to six equivalent O2- atoms to form YO6 octahedra that share corners with six equivalent PtO6 octahedra and faces with eight BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. All Y–O bond lengths are 2.21 Å. In the second Y3+ site, Y3+ is bonded to six equivalent O2- atoms to form YO6 octahedra that share corners with six equivalent RuO6 octahedra and faces with eight BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 3°. All Y–O bond lengths are 2.23 Å. Ru5+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with three equivalent BaO12 cuboctahedra, corners with three equivalent YO6 octahedra, faces with seven BaO12 cuboctahedra, and a faceface with one PtO6 octahedra. The corner-sharing octahedral tilt angles are 3°. There are three shorter (1.95 Å) and three longer (2.05 Å) Ru–O bond lengths. Pt4+ is bonded to six O2- atoms to form PtO6 octahedra that share corners with three equivalent BaO12 cuboctahedra, corners with three equivalent YO6 octahedra, faces with seven BaO12 cuboctahedra, and a faceface with one RuO6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are three shorter (2.00 Å) and three longer (2.08 Å) Pt–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four Ba2+, one Y3+, and one Ru5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to four Ba2+, one Y3+, and one Pt4+ atom. In the third O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+, one Ru5+, and one Pt4+ atom.
