K K B Au
K2AuB crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2AuB clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one B(1) atom. The K(1)-B(1) bond length is 1.59 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 1.92 Å. Au(1) is bonded in a distorted bent 150 degrees geometry to one K(2) and one B(1) atom. The Au(1)-B(1) bond length is 1.96 Å. B(1) is bonded in a distorted bent 120 degrees geometry to one K(1) and one Au(1) atom.
