V As As Se
VAs2Se crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one VAs2Se cluster. V(1) is bonded in a distorted single-bond geometry to one As(2) and one Se(1) atom. The V(1)-As(2) bond length is 1.73 Å. The V(1)-Se(1) bond length is 0.92 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted single-bond geometry to one Se(1) atom. The As(1)-Se(1) bond length is 1.80 Å. In the second As site, As(2) is bonded in a distorted single-bond geometry to one V(1) atom. Se(1) is bonded in a single-bond geometry to one V(1) and one As(1) atom.
