The crystal structure described by TmAgCu4 crystallizes in the cubic F-43m space group. Tm(1) is bonded in a 16-coordinate geometry to four equivalent Ag(1) and twelve equivalent Cu(1) atoms. Ag(1) is bonded in a 16-coordinate geometry to four equivalent Tm(1) and twelve equivalent Cu(1) atoms. Cu(1) is bonded to three equivalent Tm(1), three equivalent Ag(1), and six equivalent Cu(1) atoms to form a mixture of face, corner, and edge-sharing CuTm3Cu6Ag3 cuboctahedra. is represented by the CIF file [CIF]
