Abstract
The new complex [V(C5H5)2Br]2(μ2-F)2[V(C5H5)Br]+[BF4]− 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 P21/m, with a=7.66490(10) Å, b=15.2457(2) Å, c=13.3185(2) Å, and β=101.2721(8)° at 150(1) K.
