The material described by Sm2CoIn8 crystallizes in the tetragonal P4/mmm space group. Sm(1) is bonded to four equivalent In(1), four equivalent In(2), and four equivalent In(3) atoms to form SmIn12 cuboctahedra that share corners with eight equivalent Sm(1)In12 cuboctahedra, edges with four equivalent In(3)Sm4In8 cuboctahedra, edges with eight equivalent In(2)Sm4In8 cuboctahedra, faces with four equivalent In(2)Sm4In8 cuboctahedra, faces with four equivalent In(3)Sm4In8 cuboctahedra, and faces with five equivalent Sm(1)In12 cuboctahedra. Co(1) is bonded in a body-centered cubic geometry to eight equivalent In(1) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 11-coordinate geometry to two equivalent Sm(1), two equivalent Co(1), two equivalent In(3), and five equivalent In(1) atoms. In the second In site, In(2) is bonded to four equivalent Sm(1), four equivalent In(2), and four equivalent In(3) atoms to form distorted InSm4In8 cuboctahedra that share corners with four equivalent In(2)Sm4In8 cuboctahedra, edges with eight equivalent Sm(1)In12 cuboctahedra, edges with eight equivalent In(3)Sm4In8 cuboctahedra, faces with four equivalent Sm(1)In12 cuboctahedra, faces with four equivalent In(3)Sm4In8 cuboctahedra, and faces with eight equivalent In(2)Sm4In8 cuboctahedra.
