Materials Data on Th3Ti by Materials Project
Th3Ti is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Th is bonded to eight equivalent Th and four equivalent Ti atoms to form distorted ThTh8Ti4 cuboctahedra that share corners with four equivalent TiTh12 cuboctahedra, corners with fourteen equivalent ThTh8Ti4 cuboctahedra, edges with six equivalent TiTh12 cuboctahedra, edges with twelve equivalent ThTh8Ti4 cuboctahedra, faces with four equivalent TiTh12 cuboctahedra, and faces with sixteen equivalent ThTh8Ti4 cuboctahedra. There are a spread of Th–Th bond distances ranging from 3.26–3.62 Å. There are two shorter (3.39 Å) and two longer (3.45 Å) Th–Ti bond lengths. Ti is bonded to twelve equivalent Th atoms to form TiTh12 cuboctahedra that share corners with six equivalent TiTh12 cuboctahedra, corners with twelve equivalent ThTh8Ti4 cuboctahedra, edges with eighteen equivalent ThTh8Ti4 cuboctahedra, faces with eight equivalent TiTh12 cuboctahedra, and faces with twelve equivalent ThTh8Ti4 cuboctahedra.
