Cs Ru Ru Ru Pt
CsRu3Pt is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Cs(1) is bonded to twelve equivalent Ru(1) atoms to form CsRu12 cuboctahedra that share corners with twelve equivalent Cs(1)Ru12 cuboctahedra, faces with six equivalent Cs(1)Ru12 cuboctahedra, and faces with eight equivalent Pt(1)Ru6 octahedra. There are a spread of Cs(1)-Ru(1) bond distances ranging from 3.52-3.55 Å. Ru(1) is bonded to four equivalent Cs(1) and two equivalent Pt(1) atoms to form a mixture of corner, edge, and face-sharing RuCs4Pt2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. There is one shorter (2.49 Å) and one longer (2.51 Å) Ru(1)-Pt(1) bond length. Pt(1) is bonded to six equivalent Ru(1) atoms to form PtRu6 octahedra that share corners with six equivalent Pt(1)Ru6 octahedra and faces with eight equivalent Cs(1)Ru12 cuboctahedra. The corner-sharing octahedra are not tilted.
