Penta­aqua­oxovanadium(IV) bis(trifluoro­methane­sulfonate)

The structure of the penta­aqua­oxo­vanadium(IV) ion in a salt with singly charged counter‐ions is presented. In [VO(H₂O)₅](CF₃SO₃)₂, the six‐coordinate V atom is coordinated to the oxo group with a short bond [1.577 (2) Å]. The equatorial V—O bond lengths are 2.0262 (18) and 2.0277 (17) Å. The aqua ligand trans to the oxo group is subject to its trans influence, which leads to a somewhat longer V—O bond [2.175 (2) Å]. In the structure, the cation and both anions are situated on crystallographic mirror planes. The cation and anions engage in a number of relatively long hydrogen bonds [2.725 (2)–2.834 (2) Å].
