VMoSe2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one VMoSe2 cluster. V(1) is bonded in a distorted single-bond geometry to one Mo(1), one Se(1), and one Se(2) atom. The V(1)-Mo(1) bond length is 0.89 Å. The V(1)-Se(1) bond length is 0.60 Å. The V(1)-Se(2) bond length is 2.10 Å. Mo(1) is bonded in a distorted single-bond geometry to one V(1) atom. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a single-bond geometry to one V(1) atom. In the second Se site, Se(2) is bonded in a distorted single-bond geometry to one V(1) atom.
