The crystal structure described by TmAu3 is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. Tm(1) is bonded to four equivalent Au(1) and eight equivalent Au(2) atoms to form a mixture of corner, edge, and face-sharing TmAu12 cuboctahedra. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted see-saw-like geometry to four equivalent Tm(1) atoms. In the second Au site, Au(2) is bonded in a 4-coordinate geometry to four equivalent Tm(1) atoms. is represented by the CIF card [CIF]
