Sr Li Li Li Pt
Li3SrPt is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Li(1) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Pt(1) atoms. There are a spread of Li(1)-Sr(1) bond distances ranging from 3.08-3.83 Å. There is one shorter (2.18 Å) and one longer (2.71 Å) Li(1)-Pt(1) bond length. Sr(1) is bonded to twelve equivalent Li(1) atoms to form distorted SrLi12 cuboctahedra that share corners with twelve equivalent Sr(1)Li12 cuboctahedra, faces with six equivalent Sr(1)Li12 cuboctahedra, and faces with eight equivalent Pt(1)Li6 octahedra. Pt(1) is bonded to six equivalent Li(1) atoms to form PtLi6 octahedra that share corners with six equivalent Pt(1)Li6 octahedra and faces with eight equivalent Sr(1)Li12 cuboctahedra. The corner-sharing octahedra are not tilted.
