Ba V V Ge
BaV2Ge crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaV2Ge clusters. Ba(1) is bonded in a single-bond geometry to one V(1) atom. The Ba(1)-V(1) bond length is 1.61 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded in a distorted single-bond geometry to one Ba(1) and one V(2) atom. The V(1)-V(2) bond length is 1.67 Å. In the second V site, V(2) is bonded in a 2-coordinate geometry to one V(1) and one Ge(1) atom. The V(2)-Ge(1) bond length is 2.23 Å. Ge(1) is bonded in a single-bond geometry to one V(2) atom.
