Ba Ba Rh
Ba2Rh crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ba2Rh clusters. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a single-bond geometry to one Rh(1) atom. The Ba(1)-Rh(1) bond length is 0.57 Å. In the second Ba site, Ba(2) is bonded in a single-bond geometry to one Rh(1) atom. The Ba(2)-Rh(1) bond length is 2.83 Å. Rh(1) is bonded in a single-bond geometry to one Ba(1) and one Ba(2) atom.
