Materials Data on U3Ti by Materials Project
U3Ti crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. U is bonded to eight equivalent U and four equivalent Ti atoms to form distorted UU8Ti4 cuboctahedra that share corners with four equivalent TiU12 cuboctahedra, corners with fourteen equivalent UU8Ti4 cuboctahedra, edges with six equivalent TiU12 cuboctahedra, edges with twelve equivalent UU8Ti4 cuboctahedra, faces with four equivalent TiU12 cuboctahedra, and faces with sixteen equivalent UU8Ti4 cuboctahedra. There are a spread of U–U bond distances ranging from 2.75–3.23 Å. There are two shorter (2.95 Å) and two longer (3.10 Å) U–Ti bond lengths. Ti is bonded to twelve equivalent U atoms to form TiU12 cuboctahedra that share corners with six equivalent TiU12 cuboctahedra, corners with twelve equivalent UU8Ti4 cuboctahedra, edges with eighteen equivalent UU8Ti4 cuboctahedra, faces with eight equivalent TiU12 cuboctahedra, and faces with twelve equivalent UU8Ti4 cuboctahedra.
