Solid State Structure of Bis[(bromo)(dicyclopentadienyl)vanadium(μ₂-fluoro)][(bromo)(cyclopentadienyl)vanadium][tetrafluoroborate]

Abstract

− has been isolated from the reaction of vanadocene monobromide with the ferrocenium cation. The complex is a mixed valence compound composed of two V(IV) and one V(III) centers. The V(III) center has one cyclopentadienyl ligand in its coordination sphere, as well as a bromide and two fluoride ligands. Each fluoride ligand is also attached to one of the V(IV) centers, which additionally is coordinated by a bromide and two cyclopentadienyl ligands. The complex crystallizes in the monoclinic space group 2 1 / , with = 7.66490(10)Å, = 15.2457(2)Å, = 13.3185(2)Å, and = 101.2721(8) ∘ at 150(1) K.
