KAu2In crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KAu2In clusters. K(1) is bonded in a distorted bent 150 degrees geometry to one Au(2) and one In(1) atom. The K(1)-Au(2) bond length is 2.36 Å. The K(1)-In(1) bond length is 1.39 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a single-bond geometry to one Au(2) atom. The Au(1)-Au(2) bond length is 0.40 Å. In the second Au site, Au(2) is bonded in a bent 150 degrees geometry to one K(1) and one Au(1) atom. In(1) is bonded in a single-bond geometry to one K(1) atom.
