Ba Na Rh Rh
NaBaRh2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaBaRh2 clusters. Na(1) is bonded in a 3-coordinate geometry to one Ba(1) and two equivalent Rh(1) atoms. The Na(1)-Ba(1) bond length is 1.08 Å. Both Na(1)-Rh(1) bond lengths are 1.44 Å. Ba(1) is bonded in a 3-coordinate geometry to one Na(1) and two equivalent Rh(1) atoms. Both Ba(1)-Rh(1) bond lengths are 1.44 Å. Rh(1) is bonded in a 3-coordinate geometry to one Na(1), one Ba(1), and one Rh(1) atom. The Rh(1)-Rh(1) bond length is 1.08 Å.
