Lu3Sn is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Lu(1) is bonded to eight equivalent Lu(1) and four equivalent Sn(1) atoms to form distorted LuLu8Sn4 cuboctahedra that share corners with four equivalent Sn(1)Lu12 cuboctahedra, corners with fourteen equivalent Lu(1)Lu8Sn4 cuboctahedra, edges with six equivalent Sn(1)Lu12 cuboctahedra, edges with twelve equivalent Lu(1)Lu8Sn4 cuboctahedra, faces with four equivalent Sn(1)Lu12 cuboctahedra, and faces with sixteen equivalent Lu(1)Lu8Sn4 cuboctahedra. Sn(1) is bonded to twelve equivalent Lu(1) atoms to form SnLu12 cuboctahedra that share corners with six equivalent Sn(1)Lu12 cuboctahedra, corners with twelve equivalent Lu(1)Lu8Sn4 cuboctahedra, edges with eighteen equivalent Lu(1)Lu8Sn4 cuboctahedra, faces with eight equivalent Sn(1)Lu12 cuboctahedra, and faces with twelve equivalent Lu(1)Lu8Sn4 cuboctahedra.

There are a spread of Lu(1)-Lu(1) bond distances ranging from 3.30-3.41 Å. There are two shorter (3.33 Å) and two longer (3.35 Å) Lu(1)-Sn(1) bond lengths. Sn(1) is bonded to twelve equivalent Lu(1) atoms to form SnLu12 cuboctahedra that share corners with six equivalent Sn(1)Lu12 cuboctahedra, corners with twelve equivalent Lu(1)Lu8Sn4 cuboctahedra, edges with eighteen equivalent Lu(1)Lu8Sn4 cuboctahedra, faces with eight equivalent Sn(1)Lu12 cuboctahedra, and faces with twelve equivalent Lu(1)Lu8Sn4 cuboctahedra.
