vanadiumIIkloridi

Vanadium(II) chloride is the chemical compound with the formula VCl2. It is a yellow, crystalline solid that is highly soluble in water. Vanadium(II) chloride is a strong reducing agent and is often used in organic synthesis.

Vanadium(II) chloride can be prepared by the reduction of vanadium(V) oxide with hydrogen chloride. The reaction is as follows:

2V2O5 + 10HCl -> 4VCl2 + 5H2O + 2Cl2

Vanadium(II) chloride is a diamagnetic compound. It has a layered structure in the solid state, with each vanadium atom octahedrally coordinated by six chloride ions.

Vanadium(II) chloride is an important intermediate in the production of other vanadium compounds. It is also used as a catalyst in some organic reactions, such as the Diels-Alder reaction. In addition, vanadium(II) chloride can be used to prepare vanadium metal by reduction with magnesium.

Vanadium(II) chloride is a relatively stable compound, but it can be oxidized by air to form vanadium(III) chloride. It can also react with water to form vanadium(II) hydroxide.
