VOsSe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two VOsSe clusters. V(1) is bonded in a single-bond geometry to one Se(1) atom. The V(1)-Se(1) bond length is 0.36 Å. Os(1) is bonded in a distorted single-bond geometry to one Se(1) atom. The Os(1)-Se(1) bond length is 0.12 Å. Se(1) is bonded in a linear geometry to one V(1) and one Os(1) atom.
