Vanadium ( II) chloride is an inorganic chemical compound consisting of the group of the chlorides. It is a light yellow solid which sublimates from 910 ° C.
History
Production and representation
Vanadium ( II) chloride may be recovered in the presence of oxygen- hydrogen by reduction of vanadium (III ) chloride by heating ( 675 ° C ~ ).
The disproportionation of vanadium ( III) chloride in a nitrogen
Or the direct reaction of vanadium with chlorine are also possible.
Properties
Vanadium (II ) chloride is a light green leaflets. It is less hygroscopic than the vanadium (III) - and vanadium (IV ) chloride and does not dissolve in alcohol or ether. It is a strong reducing agent with which the reduction of sulfoxides to sulfides, organic azides to amines, as well as the reductive coupling of alkyl halides to some possible. In solution in water, the [V (H2O) 6] 2 ion forms.
Vanadium ( II) chloride, having an octahedral crystal structure with space group P3m1, similar to that of cadmium iodide.
