'''Vanadium(II) oxide''', VO, is one of the many ]. VO is a long-lived, electronically neutral reagent chemical. It adopts a distorted ] 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 ], its composition varying from VO<sub>0.8</sub> to VO<sub>1.3</sub><ref>{{Greenwood&Earnshaw2nd|page=982}}</ref>. |
