Vanadium oxide, VO, is one of the many oxides of vanadium

Vanadium oxide

Vanadium oxide may refer to:* Vanadium oxide , VO* Vanadium oxide , V2O3* Vanadium oxide , VO2* Vanadium oxide , V2O5...

. VO is a long-lived, electronically neutral reagent chemical. It adopts a distorted NaCl structure and contains weak V-V metal to metal bonds. As shown by band theory, VO is a conductor of electricity due to its partially filled conduction band and delocalisation of electrons in the t2g orbitals. VO is a non-stoichiometric compound

Non-stoichiometric compound

Non-stoichiometric compounds are chemical compounds with an elemental composition that cannot be represented by a ratio of well-defined natural numbers, and therefore violate the law of definite proportions. Often, they are solids that contain crystallographic point defects, such as interstitial...
