V Zn Se
VZnSe is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one VZnSe cluster. V(1) is bonded in a single-bond geometry to one Se(1) atom. The V(1)-Se(1) bond length is 0.93 Å. Zn(1) is bonded in a single-bond geometry to one Se(1) atom. The Zn(1)-Se(1) bond length is 1.46 Å. Se(1) is bonded in a distorted bent 150 degrees geometry to one V(1) and one Zn(1) atom.
