K2RhB is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two 7440-42-8 atoms and two K2Rh clusters. In each K2Rh cluster, there are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Rh(1) atom. The K(1)-Rh(1) bond length is 0.76 Å. In the second K site, K(2) is bonded in a single-bond geometry to one Rh(1) atom. The K(2)-Rh(1) bond length is 0.52 Å. Rh(1) is bonded in a linear geometry to one K(1) and one K(2) atom.
