Vanadium(II) oxide is the inorganic compound with the idealized formula VO. It is one of the several binary vanadium oxides. It adopts a distorted NaCl structure and contains weak V−V metal to metal bonds. VO is a semiconductor owing to delocalisation of electrons in the t2g orbitals. VO is a non-stoichiometric compound, its composition varying from VO0.8 to VO1.3.[2]
Diatomic VO is one of the molecules found in the spectrum of relatively cool M-type stars.[3] A potential use of vanadium(II) monoxide is as a molecular vapor in synthetic chemicalreagents in low-temperature matrices.[4]
