text: # Vanadium(II) oxide
  
  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 $t_{2g}$ orbitals. VO is a non-stoichiometric compound, its composition varying from $VO_{0.8}$ to $VO_{1.3}.$
  
  Diatomic VO is one of the molecules found in the spectrum of relatively cool M-type stars. A potential use of vanadium(II) monoxide is as a molecular vapor in synthetic chemical reagents in low-temperature matrices.
