VSiCl2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two VSiCl2 clusters. V(1) is bonded in a linear geometry to one Cl(1) and one Cl(2) atom. The V(1)-Cl(1) bond length is 1.39 Å. The V(1)-Cl(2) bond length is 1.39 Å. Si(1) is bonded in a single-bond geometry to one Cl(1) atom. The Si(1)-Cl(1) bond length is 1.51 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a linear geometry to one V(1) and one Si(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one V(1) atom.
