K2AuB is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one K2AuB cluster. There are four inequivalent K sites. In the first K site, K(1) is bonded in a distorted single-bond geometry to one K(4), one B(1), and one B(2) atom. The K(1)-K(4) bond length is 0.32 Å. The K(1)-B(1) bond length is 1.67 Å. The K(1)-B(2) bond length is 2.00 Å. In the second K site, K(2) is bonded in a single-bond geometry to one K(3) and one B(1) atom. The K(2)-K(3) bond length is 0.32 Å. The K(2)-B(1) bond length is 2.00 Å. In the third K site, K(3) is bonded in a single-bond geometry to one K(2) and one B(2) atom. The K(3)-B(2) bond length is 1.75 Å. In the fourth K site, K(4) is bonded in a distorted single-bond geometry to one K(1) and one B(1) atom. The K(4)-B(1) bond length is 1.75 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) and one B(1) atom. The Au(1)-Au(2) bond length is 0.19 Å. The Au(1)-B(1) bond length is 2.27 Å. In the second Au site, Au(2) is bonded in a single-bond geometry to one Au(1) and one B(1) atom. The Au(2)-B(1) bond length is 2.26 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 6-coordinate geometry to one K(1), one K(2), one K(4), one Au(1), one Au(2), and one B(2) atom. The B(1)-B(2) bond length is 0.84 Å. In the second B site, B(2) is bonded in a 3-coordinate geometry to one K(1), one K(3), and one B(1) atom.
