NbW2Rh crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NbW2Rh clusters. Nb(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms. Both Nb(1)-W(1) bond lengths are 0.84 Å. W(1) is bonded in a distorted single-bond geometry to one Nb(1), one W(1), and one Rh(1) atom. The W(1)-W(1) bond length is 0.25 Å. The W(1)-Rh(1) bond length is 0.53 Å. Rh(1) is bonded in a 2-coordinate geometry to two equivalent W(1) atoms.
