TcOs2Au crystallizes in the trigonal R3m space group. Tc(1) is bonded in a single-bond geometry to three equivalent Os(1) and one Au(1) atom. All Tc(1)-Os(1) bond lengths are 2.77 Å. The Tc(1)-Au(1) bond length is 1.54 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 7-coordinate geometry to three equivalent Tc(1), one Os(2), and three equivalent Au(1) atoms. The Os(1)-Os(2) bond length is 1.54 Å. All Os(1)-Au(1) bond lengths are 2.77 Å. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to one Os(1) atom. Au(1) is bonded in a single-bond geometry to one Tc(1) and three equivalent Os(1) atoms.
