Mg V V Sn
MgV2Sn is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgV2Sn cluster. Mg(1) is bonded in a 2-coordinate geometry to one V(2) and one Sn(1) atom. The Mg(1)-V(2) bond length is 0.32 Å. The Mg(1)-Sn(1) bond length is 0.32 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 2-coordinate geometry to one V(2) and one Sn(1) atom. The V(1)-V(2) bond length is 0.41 Å. The V(1)-Sn(1) bond length is 0.41 Å. In the second V site, V(2) is bonded in a single-bond geometry to one Mg(1), one V(1), and one Sn(1) atom. The V(2)-Sn(1) bond length is 0.07 Å. Sn(1) is bonded in a single-bond geometry to one Mg(1), one V(1), and one V(2) atom.
