The compound described by Ce2(InSn)3 is beta Cu3Ti-derived structured and crystallizes in the orthorhombic Pmmm space group. Ce(1) is bonded to two equivalent In(2), four equivalent In(1), two equivalent Sn(1), two equivalent Sn(2), and two equivalent Sn(3) atoms to form CeIn6Sn6 cuboctahedra that share corners with twelve equivalent Ce(1)In6Sn6 cuboctahedra, edges with four equivalent In(2)Ce4In4Sn4 cuboctahedra, edges with four equivalent Sn(2)Ce4In8 cuboctahedra, edges with eight equivalent In(1)Ce4In2Sn6 cuboctahedra, faces with two equivalent In(2)Ce4In4Sn4 cuboctahedra, faces with two equivalent Sn(2)Ce4In8 cuboctahedra, faces with four equivalent In(1)Ce4In2Sn6 cuboctahedra, and faces with six equivalent Ce(1)In6Sn6 cuboctahedra. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent Ce(1), two equivalent In(2), two equivalent Sn(1), two equivalent Sn(2), and two equivalent Sn(3) atoms to form InCe4In2Sn6 cuboctahedra that share corners with twelve equivalent In(1)Ce4In2Sn6 cuboctahedra, edges with four equivalent In(2)Ce4In4Sn4 cuboctahedra, edges with four equivalent Sn(2)Ce4In8 cuboctahedra, edges with eight equivalent Ce(1)In6Sn6 cuboctahedra, faces with two equivalent In(2)Ce4In4Sn4 cuboctahedra, faces with two equivalent Sn(2)Ce4In8 cuboctahedra, faces with four equivalent Ce(1)In6Sn6 cuboctahedra, and faces with six equivalent In(1)Ce4In2Sn6 cuboctahedra. In the second In site, In(2) is bonded to four equivalent Ce(1), four equivalent In(1), and four equivalent Sn(2) atoms to form distorted InCe4In4Sn4 cuboctahedra that share corners with four equivalent In(2)Ce4In4Sn4 cuboctahedra, edges with eight equivalent Ce(1)In6Sn6 cuboctahedra, edges with eight equivalent In(1)Ce4In2Sn6 cuboctahedra, faces with four equivalent Ce(1)In6Sn6 cuboctahedra, faces with four equivalent In(1)Ce4In2Sn6 cuboctahedra, faces with four equivalent In(2)Ce4In4Sn4 cuboctahedra, and faces with four equivalent Sn(2)Ce4In8 cuboctahedra. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1), four equivalent In(1), and four equivalent Sn(3) atoms. In the second Sn site, Sn(2) is bonded to four equivalent Ce(1), four equivalent In(1), and four equivalent In(2) atoms to form SnCe4In8 cuboctahedra that share corners with four equivalent Sn(2)Ce4In8 cuboctahedra, edges with eight equivalent Ce(1)In6Sn6 cuboctahedra, edges with eight equivalent In(1)Ce4In2Sn6 cuboctahedra, faces with four equivalent Ce(1)In6Sn6 cuboctahedra, faces with four equivalent In(1)Ce4In2Sn6 cuboctahedra, faces with four equivalent In(2)Ce4In4Sn4 cuboctahedra, and faces with four equivalent Sn(2)Ce4In8 cuboctahedra.
