K2OsB crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one K2OsB cluster. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Os(1) atom. The K(1)-Os(1) bond length is 1.85 Å. In the second K site, K(2) is bonded in a distorted bent 150 degrees geometry to one Os(1) and one B(1) atom. The K(2)-Os(1) bond length is 1.85 Å. The K(2)-B(1) bond length is 1.62 Å. Os(1) is bonded in a bent 150 degrees geometry to one K(1) and one K(2) atom. B(1) is bonded in a single-bond geometry to one K(2) atom.
