V V V Bi
V3Bi crystallizes in the monoclinic Cm space group. There are three inequivalent V sites. In the first V site, V(1) is bonded in a distorted single-bond geometry to one V(3) and one Bi(1) atom. The V(1)-V(3) bond length is 2.44 Å. The V(1)-Bi(1) bond length is 2.24 Å. In the second V site, V(2) is bonded in a single-bond geometry to three equivalent V(3) and one Bi(1) atom. There is one shorter (1.80 Å) and two longer (2.74 Å) V(2)-V(3) bond lengths. The V(2)-Bi(1) bond length is 0.66 Å. In the third V site, V(3) is bonded in a 4-coordinate geometry to one V(1) and three equivalent V(2) atoms. Bi(1) is bonded in a single-bond geometry to one V(1) and one V(2) atom.
