Vanadium oxydichloride is the inorganic compound with the formula VOCl 2. One of several oxychlorides of vanadium, it is a hygroscopic green solid. It is prepared by comproportionation of vanadium trichloride and vanadium(V) oxides: [1] V 2 O 5 + VOCl 3 + 3 VCl 3 → 6 VOCl 2
VOCl 3 quickly hydrolyzes resulting in vanadium pentoxide and hydrochloric acid.An intermediate in this process is VO 2 Cl: . 2 VOCl 3 + 3 H 2 O → V 2 O 5 + 6 HCl. VOCl 3 reacts with alcohols especially in the presence of a proton-acceptor to give alkoxides, as illustrated by this synthesis of vanadyl isopropoxide:

Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V 2 O 5.Commonly known as vanadium pentoxide, it is a dark yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange.
Heating a suspension of vanadium pentoxide and phosphoric acid gives VOPO 4 •2H 2 O, isolated as a bright yellow solid. [4] According to X-ray crystallography, the V(V) centers are octahedral, with long, weak bonds to aquo ligands.
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]
