U3Ti crystallizes in the hexagonal P6_3/mmc space group. U(1) is bonded to eight equivalent U(1) and four equivalent Ti(1) atoms to form distorted UU8Ti4 cuboctahedra that share corners with four equivalent Ti(1)U12 cuboctahedra, corners with fourteen equivalent U(1)U8Ti4 cuboctahedra, edges with six equivalent Ti(1)U12 cuboctahedra, edges with twelve equivalent U(1)U8Ti4 cuboctahedra, faces with four equivalent Ti(1)U12 cuboctahedra, and faces with sixteen equivalent U(1)U8Ti4 cuboctahedra. Ti(1) is bonded to twelve equivalent U(1) atoms to form TiU12 cuboctahedra that share corners with six equivalent Ti(1)U12 cuboctahedra, corners with twelve equivalent U(1)U8Ti4 cuboctahedra, edges with eighteen equivalent U(1)U8Ti4 cuboctahedra, faces with eight equivalent Ti(1)U12 cuboctahedra, and faces with twelve equivalent U(1)U8Ti4 cuboctahedra.

There are a spread of U(1)-U(1) bond distances ranging from 2.75-3.23 Å. There are two shorter (2.95 Å) and two longer (3.10 Å) U(1)-Ti(1) bond lengths. Ti(1) is bonded to twelve equivalent U(1) atoms to form TiU12 cuboctahedra that share corners with six equivalent Ti(1)U12 cuboctahedra, corners with twelve equivalent U(1)U8Ti4 cuboctahedra, edges with eighteen equivalent U(1)U8Ti4 cuboctahedra, faces with eight equivalent Ti(1)U12 cuboctahedra, and faces with twelve equivalent U(1)U8Ti4 cuboctahedra.
