In3Sn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. In(1) is bonded to eight equivalent In(1) and four equivalent Sn(1) atoms to form InIn8Sn4 cuboctahedra that share corners with twelve equivalent In(1)In8Sn4 cuboctahedra, edges with eight equivalent Sn(1)In12 cuboctahedra, edges with sixteen equivalent In(1)In8Sn4 cuboctahedra, faces with four equivalent Sn(1)In12 cuboctahedra, and faces with fourteen equivalent In(1)In8Sn4 cuboctahedra. Sn(1) is bonded to twelve equivalent In(1) atoms to form SnIn12 cuboctahedra that share corners with twelve equivalent Sn(1)In12 cuboctahedra, edges with twenty-four equivalent In(1)In8Sn4 cuboctahedra, faces with six equivalent Sn(1)In12 cuboctahedra, and faces with twelve equivalent In(1)In8Sn4 cuboctahedra.
