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 ...
The vanadyl or oxovanadium(IV) cation, VO 2+, [1] is a functional group that is common in the coordination chemistry of vanadium. Complexes containing this functional group are characteristically blue and paramagnetic. A triple bond is proposed to exist between the V 4+ and O 2− centers. [2]
The melting point of Vanadium(V) chloride chlorimide is 136 °C. It can be sublimed in a vacuum below its melting point. The density of the solid is 2.48. [5] The solid has a triclinic crystal structure with unit cell a=7.64, b=7.14, c=5.91 Å; α=112.4°, β=94.9°, γ=107.8° with Z=2 (formulas per unit cell). [6] The space group is P 1. [7]
