CoAu4In is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three CoAu4In clusters. Co(1) is bonded in a single-bond geometry to one In(1) atom. The Co(1)-In(1) bond length is 0.75 Å. There are two inequivalent Au sites. In the first Au site, Au(2) is bonded in a 3-coordinate geometry to three equivalent Au(1) atoms. All Au(2)-Au(1) bond lengths are 0.49 Å. In the second Au site, Au(1) is bonded in a 2-coordinate geometry to one Au(2), two equivalent Au(1), and one In(1) atom. Both Au(1)-Au(1) bond lengths are 0.28 Å. The Au(1)-In(1) bond length is 0.66 Å. In(1) is bonded in a distorted rectangular see-saw-like geometry to one Co(1) and three equivalent Au(1) atoms.
