Vanadium(III) chloride describes the inorganic compound with the formula VCl 3 and its hydrates. It forms a purple anhydrous form and a green hexahydrate [VCl 2 (H 2 O) 4 ]Cl·2H 2 O. These hygroscopic salts are common precursors to other vanadium(III) complexes and is used as a mild reducing agent .
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 .
Vanadium(II) chloride is the inorganic compound with the formula VCl 2, and is the most reduced vanadium chloride. Vanadium(II) chloride is an apple-green solid that dissolves in water to give purple solutions.
The chemistry of vanadium is noteworthy for the accessibility of the four adjacent oxidation states 2–5. In an aqueous solution, vanadium forms metal aquo complexes of which the colors are lilac [V(H 2 O) 6] 2+, green [V(H 2 O) 6] 3+, blue [VO(H 2 O) 5] 2+, yellow-orange oxides [VO(H 2 O) 5] 3+, the formula for which depends on pH. Vanadium ...

From left: [V(H 2 O) 6] 2+ (lilac), [V(H 2 O) 6] 3+ (green), [VO(H 2 O) 5] 2+ (blue) and [VO(H 2 O) 5] 3+ (yellow).. 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 ...

Vanadium forms oxides in the +2, +3, +4 and +5 oxidation states, forming vanadium(II) oxide (VO), vanadium(III) oxide (V 2 O 3), vanadium(IV) oxide (VO 2) and vanadium(V) oxide (V 2 O 5). Vanadium(V) oxide or vanadium pentoxide is the most common, being precursor to most alloys and compounds of vanadium, and is also a widely used industrial ...
