The vanadium oxides can also be used to produce vanadium(III) chloride. For example, vanadium(III) oxide reacts with thionyl chloride at 200 °C: [15] V 2 O 3 + 3 SOCl 2 → 2 VCl 3 + 3 SO 2. The reaction of vanadium(V) oxide and disulfur dichloride also produces vanadium(III) chloride with the release of sulfur dioxide and sulfur. [15]
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(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(V) oxide is a catalyst in the contact process for producing sulfuric acid. Vanadium compounds are used extensively as catalysts; [83] Vanadium pentoxide V 2 O 5, is used as a catalyst in manufacturing sulfuric acid by the contact process [84] In this process sulfur dioxide (SO 2) is oxidized to the trioxide (SO
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 complexes [V(CN) 6] 3− and [V 2 Cl 9] 3− are referred to as hexacyanovanadate(III) and nonachlorodivanadate(III), respectively. A simple vanadate ion is the tetrahedral orthovanadate anion, VO 3− 4 (which is also called vanadate(V)), which is present in e.g. sodium orthovanadate and in solutions of V 2 O 5 in strong base ( pH > 13 [ 1
Vanadium tetrachloride is the inorganic compound with the formula V Cl 4. This reddish-brown liquid serves as a useful reagent for the preparation of other vanadium compounds. Synthesis, bonding, basic properties
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]
