Vanadium hexacarbonyl is the inorganic compound with the formula V(CO)6. It is a blue-black volatile solid. This highly reactive species is noteworthy from theoretical perspectives as a rare isolable homoleptic metal carbonyl that is paramagnetic. Most species with the formula Mx(CO)y follow the 18e rule, whereas V(CO)6 has 17 valence electrons.〔C. Elschenbroich, A. Salzer ”Organometallics : A Concise Introduction” (2nd Ed) (1992) from Wiley-VCH: Weinheim. ISBN 3-527-28165-7〕
== Synthesis ==
Traditionally V(CO)6 is prepared in two-steps via the intermediacy of (). In the first step, VCl3 is reduced with metallic sodium under 200 atm CO at 160 °C. The solvent for this reduction is typically diglyme, CH3OCH2CH2OCH2CH2OCH3. This triether solubilizes sodium salts, akin to the behavior of a crown ether:
:4 Na + VCl3 + 6 CO + 2 diglyme → ()() + 3 NaCl
The resulting anion is oxidized with acid:〔Liu, X.; Ellis, J. E. "Hexacarbonylvanadate(1) and Hexacarbonylvanadium(0)" Inorganic Syntheses 2004, volume 34, pages 96-103. . ISBN 0-471-64750-0〕
:2 () + H3PO4 → 2 V(CO)6 + H2 + 2 H2PO4
