By the action of dilute aqueous hydrochloric acid on the two isomeric hydrates of hypovanadic acid, two isomeric forms of Vanadium Oxydichloride, VO2Cl2.8H2O, have been prepared. The green hydrate gives rise to deep green crystals, and the rose hydrate to blue crystals of the same empirical composition. Their constitutions are a matter of doubt.
In addition to the above, two other vanadium oxychlorides have been reported: V2O2Cl4.5H2O or 2VO2.4HCl.3H2O, and V2O3Cl2.4H2O or 2VO2.2HCl.3H2O. |
