Na Na Rh W
Na2WRh crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Na2WRh clusters. Na(1) is bonded in a 3-coordinate geometry to one Na(1), one W(1), and one Rh(1) atom. The Na(1)-Na(1) bond length is 0.82 Å. The Na(1)-W(1) bond length is 1.94 Å. The Na(1)-Rh(1) bond length is 1.94 Å. W(1) is bonded in a distorted single-bond geometry to two equivalent Na(1) and one Rh(1) atom. The W(1)-Rh(1) bond length is 0.82 Å. Rh(1) is bonded in a distorted single-bond geometry to two equivalent Na(1) and one W(1) atom.
