V4Au is Tungsten structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three V4Au clusters. There are two inequivalent V sites. In the first V site, V(1) is bonded in a single-bond geometry to one V(2) atom. The V(1)-V(2) bond length is 0.67 Å. In the second V site, V(2) is bonded in a distorted tetrahedral geometry to three equivalent V(1) and one Au(1) atom. The V(2)-Au(1) bond length is 2.15 Å. Au(1) is bonded in a distorted single-bond geometry to one V(2) atom.
