HfVCr is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfVCr clusters. Hf(1) is bonded in a single-bond geometry to one V(1) atom. The Hf(1)-V(1) bond length is 0.15 Å. V(1) is bonded in a linear geometry to one Hf(1) and one Cr(1) atom. The V(1)-Cr(1) bond length is 0.36 Å. Cr(1) is bonded in a single-bond geometry to one V(1) atom.
