NbW2Cd crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NbW2Cd clusters. Nb(1) is bonded in a distorted bent 120 degrees geometry to one W(2) and one Cd(1) atom. The Nb(1)-W(2) bond length is 1.76 Å. The Nb(1)-Cd(1) bond length is 0.58 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted single-bond geometry to one Cd(1) atom. The W(1)-Cd(1) bond length is 2.14 Å. In the second W site, W(2) is bonded in a distorted single-bond geometry to one Nb(1) atom. Cd(1) is bonded in a 1-coordinate geometry to one Nb(1) and one W(1) atom.
