K K Na Au
K2NaAu crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one K2NaAu cluster. There are two inequivalent K sites. In the first K site, K(1) is bonded in a linear geometry to one Na(1) and one Au(1) atom. The K(1)-Na(1) bond length is 0.55 Å. The K(1)-Au(1) bond length is 2.34 Å. In the second K site, K(2) is bonded in a single-bond geometry to one Au(1) atom. The K(2)-Au(1) bond length is 0.59 Å. Na(1) is bonded in a single-bond geometry to one K(1) atom. Au(1) is bonded in a distorted single-bond geometry to one K(1) and one K(2) atom.
