VSe(Te)2 is Cubic alpha N2-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two selanylidenevanadium molecules and two Te clusters. In each Te cluster, there are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a single-bond geometry to one Te(2) atom. The Te(1)-Te(2) bond length is 0.23 Å. In the second Te site, Te(2) is bonded in a single-bond geometry to one Te(1) atom.
