Abstract
AbstractBis(2,2′‐bipyridine)dioxovanadium(V) trifluoromethanesulfonate, obtained from autooxidation of the corresponding oxovanadium(IV) complex, crystallizes in monoclinic, P21/n, with a = 15.433(2), b = 11.013(2), c = 27.423(2) Å, β = 104.79(2)°, Z = 4, R = 0.0697, and Rw = 0.0821. The complex consists of discrete vanadium(V) complex cations and trifluoromethanesulfonate anions. Each asymmetric unit is composed of a pair of enantiomer molecules. The octahedral vanadium complex ion, having a C2 axis, comprises a cis‐VO2, mean V‐O distance of 1.622 ± 0.007 Å, and two cis‐related 2,2′‐bipyridine ligands. The V‐N bonds trans to each other are short, with a mean V‐N distance of 2.108 ± 0.010 Å, while those trans to V=O are somewhat longer, with a mean V‐N distance of 2.292 ± 0.022 Å. The coordination geometry of the vanadium cation is very similar to that of [VO(O2)(2,2′‐bipyridine)2]+.
