A solvothermal synthesis of vanadium monoxide nanowires
from a single precursor [V(DmoxCHvCOCF3)3] was carried
out. Typically, 0.015 mol (5 mL) of oleylamine (OM) was
added to 30 mL of toluene solution containing 1.06 g
[V(DmoxCHvCOCF3)3] complex under stirring. The reaction
solution was transferred to a 60 mL Teflon-tube positioned in
a stainless-steel autoclave and heated at 250 °C for 10 h. The
reaction system was cooled to room temperature and the
vanadium(II) oxide product was centrifuged (11 000 rpm) and
washed several times with ethanol and dried in a desiccator.
The dried vanadium monoxide nanowires were then calcined
at 500 °C under an argon atmosphere for 2 hours.

Computational details
Ground state electronic structure calculations have been done
with a resolution of identity Coulomb approximation40,41
using the TURBOMOLE42 program package and the TMoleX
4.143 user interface. For all atoms, the double-ξ-valence def-SV
(P)44 and the triple-ξ-valence def2-TZVP45 basis sets were used
with Becke’s gradient-corrected exchange-energy functional
BP8646 The molecules were preoptimized at the def-SV(P) level
and then optimized at the def2-TZVP-level.
