Sc3Sn is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Sc(1) is bonded to eight equivalent Sc(1) and four equivalent Sn(1) atoms to form distorted ScSc8Sn4 cuboctahedra that share corners with four equivalent Sn(1)Sc12 cuboctahedra, corners with fourteen equivalent Sc(1)Sc8Sn4 cuboctahedra, edges with six equivalent Sn(1)Sc12 cuboctahedra, edges with twelve equivalent Sc(1)Sc8Sn4 cuboctahedra, faces with four equivalent Sn(1)Sc12 cuboctahedra, and faces with sixteen equivalent Sc(1)Sc8Sn4 cuboctahedra. Sn(1) is bonded to twelve equivalent Sc(1) atoms to form SnSc12 cuboctahedra that share corners with six equivalent Sn(1)Sc12 cuboctahedra, corners with twelve equivalent Sc(1)Sc8Sn4 cuboctahedra, edges with eighteen equivalent Sc(1)Sc8Sn4 cuboctahedra, faces with eight equivalent Sn(1)Sc12 cuboctahedra, and faces with twelve equivalent Sc(1)Sc8Sn4 cuboctahedra.

There are a spread of Sc(1)-Sc(1) bond distances ranging from 3.14-3.23 Å. There are two shorter (3.17 Å) and two longer (3.19 Å) Sc(1)-Sn(1) bond lengths. Sn(1) is bonded to twelve equivalent Sc(1) atoms to form SnSc12 cuboctahedra that share corners with six equivalent Sn(1)Sc12 cuboctahedra, corners with twelve equivalent Sc(1)Sc8Sn4 cuboctahedra, edges with eighteen equivalent Sc(1)Sc8Sn4 cuboctahedra, faces with eight equivalent Sn(1)Sc12 cuboctahedra, and faces with twelve equivalent Sc(1)Sc8Sn4 cuboctahedra.
