VW2Cr crystallizes in the monoclinic Cm space group. V(1) is bonded in a 4-coordinate geometry to four equivalent W(1), four equivalent W(2), and one Cr(1) atom. There are a spread of V(1)-W(1) bond distances ranging from 1.60-2.37 Å. There are a spread of V(1)-W(2) bond distances ranging from 2.74-3.25 Å. The V(1)-Cr(1) bond length is 2.57 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 4-coordinate geometry to four equivalent V(1), one W(2), and four equivalent Cr(1) atoms. The W(1)-W(2) bond length is 2.29 Å. There are a spread of W(1)-Cr(1) bond distances ranging from 2.97-3.45 Å. In the second W site, W(2) is bonded in a 13-coordinate geometry to four equivalent V(1), one W(1), four equivalent W(2), and four equivalent Cr(1) atoms. All W(2)-W(2) bond lengths are 2.81 Å. There are a spread of W(2)-Cr(1) bond distances ranging from 2.97-3.45 Å. Cr(1) is bonded in a 13-coordinate geometry to one V(1), four equivalent W(1), four equivalent W(2), and four equivalent Cr(1) atoms. All Cr(1)-Cr(1) bond lengths are 2.81 Å.
