The material described by Tm2CoIn8 crystallizes in the tetragonal P4/mmm space group. Tm(1) is bonded to four In(1,1); four equivalent In(2); and four equivalent In(3) atoms to form TmIn12 cuboctahedra that share corners with eight equivalent Tm(1)In12 cuboctahedra, edges with four equivalent In(2)Tm4In8 cuboctahedra, edges with eight equivalent In(3)Tm4In8 cuboctahedra, faces with four equivalent In(2)Tm4In8 cuboctahedra, faces with four equivalent In(3)Tm4In8 cuboctahedra, and faces with five equivalent Tm(1)In12 cuboctahedra. Co(1) is bonded in a body-centered cubic geometry to eight In(1,1) atoms. There are four inequivalent In sites. In the first In site, In(1) is bonded in a 11-coordinate geometry to two equivalent Tm(1); two equivalent Co(1); two equivalent In(2); and five In(1,1) atoms. In the second In site, In(1) is bonded in a 11-coordinate geometry to two equivalent Tm(1); two equivalent Co(1); two equivalent In(2); and five In(1,1) atoms. In the third In site, In(2) is bonded to four equivalent Tm(1); four In(1,1); and four equivalent In(3) atoms to form distorted InTm4In8 cuboctahedra that share corners with eight equivalent In(2)Tm4In8 cuboctahedra, edges with four equivalent Tm(1)In12 cuboctahedra, edges with eight equivalent In(3)Tm4In8 cuboctahedra, faces with four equivalent Tm(1)In12 cuboctahedra, faces with four equivalent In(3)Tm4In8 cuboctahedra, and faces with five equivalent In(2)Tm4In8 cuboctahedra. In the fourth In site, In(3) is bonded to four equivalent Tm(1), four equivalent In(2), and four equivalent In(3) atoms to form distorted InTm4In8 cuboctahedra that share corners with four equivalent In(3)Tm4In8 cuboctahedra, edges with eight equivalent Tm(1)In12 cuboctahedra, edges with eight equivalent In(2)Tm4In8 cuboctahedra, faces with four equivalent Tm(1)In12 cuboctahedra, faces with four equivalent In(2)Tm4In8 cuboctahedra, and faces with eight equivalent In(3)Tm4In8 cuboctahedra. is represented by the CIF card [CIF]
