Vanadium(II) oxide

Vanadium(II) oxide, VO, is one of the many oxides of vanadium. 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 t_2g orbitals. VO is a non-stoichiometric compound, its composition varying from VO_0.8 to VO_1.3.
