Vanadium(IV) oxide or vanadium dioxide is an inorganic compound with the formula VO 2.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]
Vanadium(II) oxide is the inorganic compound with the idealized formula VO. It is one of the several binary vanadium oxides. It adopts a distorted NaCl structure and contains weak V−V metal to metal bonds. VO is a semiconductor owing to delocalisation of electrons in the t 2g orbitals.
Vanadium(IV) oxide (vanadium dioxide), VO 2; Vanadium(V) oxide (vanadium pentoxide), V 2 O 5; Various other distinct phases include: Phases with the general formula V n O 2n+1 exist between V 2 O 5 and VO 2. Examples of these phases include V 3 O 7, V 4 O 9 and V 6 O 13. [1] Phases with the general formula V n O 2n−1 exist between VO 2 and V ...
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 ...
VO 2+, often in an ionic pairing with sodium (NaH 2 VO 4), is the second most abundant transition metal in seawater, with its concentration only being exceeded by molybdenum. [4] In the ocean the average concentration is 30 nM. Some mineral water springs also contain the ion in high concentrations.
Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. [1] They are common and exist in a variety of settings and products, not limited to house mold, upholstered furniture, arts and crafts supplies, dry cleaned clothing, and cleaning supplies. [2]

Vanadyl isopropoxide is the metal alkoxide with the formula VO(O-iPr) 3 (iPr = CH(CH 3) 2). A yellow volatile liquid, it is a common alkoxide of vanadium. It is used as a reagent and as a precursor to vanadium oxides. [1] The compound is diamagnetic. It is prepared by alcoholysis of vanadyl trichloride: VOCl 3 + 3 HOCH(CH 3) 2 → VO(OCH(CH 3 ...
