K K V Cr
K2VCr is Cyanogen Chloride-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one K2VCr cluster. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Cr(1) atom. The K(1)-Cr(1) bond length is 0.14 Å. In the second K site, K(2) is bonded in a linear geometry to one V(1) and one Cr(1) atom. The K(2)-V(1) bond length is 0.20 Å. The K(2)-Cr(1) bond length is 0.14 Å. V(1) is bonded in a single-bond geometry to one K(2) atom. Cr(1) is bonded in a linear geometry to one K(1) and one K(2) atom.
