Materials Data on Sr3Tm by Materials Project
Sr3Tm is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sr is bonded to eight equivalent Sr and four equivalent Tm atoms to form distorted SrSr8Tm4 cuboctahedra that share corners with four equivalent TmSr12 cuboctahedra, corners with fourteen equivalent SrSr8Tm4 cuboctahedra, edges with six equivalent TmSr12 cuboctahedra, edges with twelve equivalent SrSr8Tm4 cuboctahedra, faces with four equivalent TmSr12 cuboctahedra, and faces with sixteen equivalent SrSr8Tm4 cuboctahedra. There are a spread of Sr–Sr bond distances ranging from 3.90–4.15 Å. There are two shorter (3.99 Å) and two longer (4.02 Å) Sr–Tm bond lengths. Tm is bonded to twelve equivalent Sr atoms to form TmSr12 cuboctahedra that share corners with six equivalent TmSr12 cuboctahedra, corners with twelve equivalent SrSr8Tm4 cuboctahedra, edges with eighteen equivalent SrSr8Tm4 cuboctahedra, faces with eight equivalent TmSr12 cuboctahedra, and faces with twelve equivalent SrSr8Tm4 cuboctahedra.
