“…5 min) -the hydrolysis product was identified by IR and UV/Vis spectroscopy as [VOCl 2 ([9]aneS 3 )]. [4,5] Attempts to abstract chloride from [VOCl 3 ([9]aneS 3 )] using FeCl 3 were unsuccessful, but when this reaction was repeated using SbCl 5 , which is a much stronger Lewis acid, the brown-purple [VOCl 2 ([9]aneS 3 )][SbCl 6 ] was formed in good yield. The complexes of the thiacrowns are very poorly soluble in chlorocarbons, which prevented solution spectroscopic studies.…”

“…[1][2][3] Examples of high oxidation state vanadium complexes with softer, neutral σ-donor ligands such as thio-or selenoethers are extremely rare -no V V derivatives are known and the only structurally characterised example with V IV is the distorted octahedral vanadyl species [VOCl 2 ([9]aneS 3 )]. [4,5] The lower oxidation state V III and V II thioether complexes are well established, [5][6][7][8] but reports of V IV thioethers contain very limited data. [9,10] We note that much early work on phosphane complexes of VCl 4 is now known to be erroneous (see for example ref.…”

The chemistry of vanadium and its complexes with various ligands is reviewed, following the format used in the corresponding article in the first edition of this Encyclopedia. The article begins with an update of the element itself. This is followed by a description of the binary compounds formed with hydride, halide, oxide, chalcogenide, nitride, and phosphide ligands. Compounds formed with carbide ligands are briefly mentioned, but thereafter carbon‐donor ligands are not included in this article. Then follows a review of the coordination chemistry of vanadium, which, after a brief introduction, is grouped into sections according to the oxidation state of vanadium in the compounds under discussion. The first section describes compounds in low oxidation states, [vanadium(−1), vanadium(0), and vanadium(1)], in which nitrogen‐donor ligands such as N 2 and NO and tertiary phosphine ligands are prominent. The second section describes the coordination chemistry of vanadium(II). This section is subdivided according to the donor atom of the various ligands that bind the metal, that is, oxygen, nitrogen, and phosphorus ligands and other ligand types, such as halides. Vanadium(III) coordination complexes comprise the next section, which is subdivided according to oxygen ligands, nitrogen ligands, sulfur ligands, and halide and other ligands. It is to be noted that in general the compounds that have thus far been described tend to be oxidized rather easily to compounds of higher oxidation states. The coordination chemistry of vanadium(IV), which comprises the next section, is dominated by the very stable VO 2+ (vanadyl) group and a separate subsection is devoted to coordination compounds that contain this grouping. The other subsections describe nonoxo complexes and halide, nitrogen, and sulfur and selenium ligands; the thiovanadyl group, VS 2+ is included in the last subsection. Oxygen‐donor ligands are also prominent in the chemistry of the highest oxidation state of vanadium(V), whose coordination chemistry is covered in the final section. Thus, separate subsections describe the coordination chemistry of the VO 3+ group, the VO 2 + unit, and peroxo‐complexes. The remaining subsections describe nonoxo complexes, nitrogen, sulfur, and selenium ligands. A feature of the development of vanadium chemistry during the years since the original article appeared has been the very large increase in the number of coordination complexes that have been prepared and structurally characterized. The content and relative sizes of the subsections of this article and the figures that are included reflect this trend.
