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.

Similar in size and charge to phosphorus(V), vanadium(V) also parallels its chemistry and crystallography. Orthovanadate V O 3− 4 is used in protein crystallography [5] to study the biochemistry of phosphate. [6] Beside that, this anion also has been shown to interact with activity of some specific enzymes.

The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers . [ 6 ]
In chemistry, a vanadate is an anionic coordination complex of vanadium. Often vanadate refers to oxoanions of vanadium, most of which exist in its highest oxidation state of +5. The complexes [V(CN) 6] 3− and [V 2 Cl 9] 3− are referred to as hexacyanovanadate(III) and nonachlorodivanadate(III), respectively.
Vanadium(IV) oxide or vanadium dioxide is an inorganic compound with the formula VO 2. It is a dark blue solid. It is a dark blue solid. Vanadium (IV) dioxide is amphoteric , dissolving in non-oxidising acids to give the blue vanadyl ion , [VO] 2+ and in alkali to give the brown [V 4 O 9 ] 2− ion, or at high pH [VO 4 ] 4− . [ 4 ]
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]
C corresponds to the electronic charge of the species relative to the site that it occupies. The charge of the species is calculated by the charge on the current site minus the charge on the original site. To continue the previous example, Ni often has the same valency as Cu, so the relative charge is zero. To indicate a null charge, × is used
