The crystal structure described by Y3Sn is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Y(1) is bonded to eight equivalent Y(1) and four equivalent Sn(1) atoms to form distorted YY8Sn4 cuboctahedra that share corners with four equivalent Sn(1)Y12 cuboctahedra, corners with fourteen equivalent Y(1)Y8Sn4 cuboctahedra, edges with six equivalent Sn(1)Y12 cuboctahedra, edges with twelve equivalent Y(1)Y8Sn4 cuboctahedra, faces with four equivalent Sn(1)Y12 cuboctahedra, and faces with sixteen equivalent Y(1)Y8Sn4 cuboctahedra. Sn(1) is bonded to twelve equivalent Y(1) atoms to form SnY12 cuboctahedra that share corners with six equivalent Sn(1)Y12 cuboctahedra, corners with twelve equivalent Y(1)Y8Sn4 cuboctahedra, edges with eighteen equivalent Y(1)Y8Sn4 cuboctahedra, faces with eight equivalent Sn(1)Y12 cuboctahedra, and faces with twelve equivalent Y(1)Y8Sn4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
