Be V V Si
BeSiV2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeSiV2 cluster. Be(1) is bonded in a 3-coordinate geometry to one V(1), one V(2), and one Si(1) atom. The Be(1)-V(1) bond length is 0.48 Å. The Be(1)-V(2) bond length is 0.97 Å. The Be(1)-Si(1) bond length is 0.97 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded in a single-bond geometry to one Be(1) atom. In the second V site, V(2) is bonded in a 1-coordinate geometry to one Be(1) atom. Si(1) is bonded in a distorted single-bond geometry to one Be(1) atom.
