V V Fe Bi
V2FeBi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two V2FeBi clusters. V(1) is bonded in a distorted single-bond geometry to one Fe(1) and one Bi(1) atom. The V(1)-Fe(1) bond length is 0.66 Å. The V(1)-Bi(1) bond length is 0.28 Å. Fe(1) is bonded in a 2-coordinate geometry to two equivalent V(1) atoms. Bi(1) is bonded in an L-shaped geometry to two equivalent V(1) atoms.
