WCdSe2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one WCdSe2 cluster. W(1) is bonded in a single-bond geometry to one Cd(1) atom. The W(1)-Cd(1) bond length is 0.20 Å. Cd(1) is bonded in a single-bond geometry to one W(1), one Se(1), and one Se(2) atom. The Cd(1)-Se(1) bond length is 3.00 Å. The Cd(1)-Se(2) bond length is 3.00 Å. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted single-bond geometry to one Cd(1) atom. In the second Se site, Se(2) is bonded in a distorted single-bond geometry to one Cd(1) atom.
