The vanadium oxides can also be used to produce vanadium(III) chloride. For example, vanadium(III) oxide reacts with thionyl chloride at 200 °C: [15] V 2 O 3 + 3 SOCl 2 → 2 VCl 3 + 3 SO 2. The reaction of vanadium(V) oxide and disulfur dichloride also produces vanadium(III) chloride with the release of sulfur dioxide and sulfur. [15]
Vanadium compounds are compounds formed by the element vanadium (V). The chemistry of vanadium is noteworthy for the accessibility of the four adjacent oxidation states 2–5, whereas the chemistry of the other group 5 elements , niobium and tantalum , are somewhat more limited to the +5 oxidation state.

Vanadium(V) chloride is the inorganic compound with the formula VCl 5. It is a black diamagnetic solid. The molecules adopt a bioctahedral structure similar to that of niobium(V) chloride .
The vanadium ion is rather large and some complexes achieve coordination numbers greater than 6, as is the case in [V(CN) 7] 4−. Oxovanadium(V) also forms 7 coordinate coordination complexes with tetradentate ligands and peroxides and these complexes are used for oxidative brominations and thioether oxidations.

Chlorate is the common name of the ClO − 3 anion, whose chlorine atom is in the +5 oxidation state.The term can also refer to chemical compounds containing this anion, with chlorates being the salts of chloric acid.
The complexes [V(CN) 6] 3− and [V 2 Cl 9] 3− are referred to as hexacyanovanadate(III) and nonachlorodivanadate(III), respectively. A simple vanadate ion is the tetrahedral orthovanadate anion, VO 3− 4 (which is also called vanadate(V)), which is present in e.g. sodium orthovanadate and in solutions of V 2 O 5 in strong base ( pH > 13 [ 1
