“…99,100 Many vanadyl [VO] 2+ complexes are known, but fluoride containing species are rare. Yellow VOF 2 , 101 blue VOF 2 ÁxH 2 O, and green [VOF 2 (LÀL)] (LÀL = 2,2 0 -bipy or 1,10-phen, formed from VOF 2 ÁxH 2 O and ligand), 102 are not well characterised. Yellow-green powders formulated as [VOF 2 (LÀL)] (LÀL = 2,2 0bipy or 1,10-phen) were reported to be formed by pyrolysis of the salts [LÀLH][VOF 3 (H 2 O)].…”

Medium and high oxidation state metal/non-metal fluoride and oxide–fluoride complexes with neutral donor ligands

While most high and medium oxidation state (O.S. ≥ 3) metal and non-metal fluorides and oxide fluorides are strong Lewis acids, exploration of their coordination chemistry with neutral ligands has been limited and mostly non-systematic. This is despite the very different properties conferred on the acceptor centre by the small electronegative fluoride ligands compared to the heavier halides. This article sets out these key differences, discusses possible synthetic routes, the key characterisation techniques, and appropriate bonding models. Current knowledge of the coordination chemistry of d, f and p-block fluorides and oxide fluorides with neutral ligands (with donor atoms drawn from Groups 15 and 16 and including N-heterocyclic carbenes) is then presented and discussed, and the differences in properties compared to complexes containing the heavier halides are illustrated. The emphasis is on work published post 1990, but earlier work is also included as essential background and where no more recent information exists. Attention is drawn to unexplored areas meriting investigation and to possible applications of these complexes.

“…The anhydrous fluoride, VOF2, is known (63,160,281,317) as well as some hydrated forms, V0F2-:rH20 (63,267,270,271,332). Recent investigation (63) of the system V02-HF-H20 by an isothermal method has established a pale blue V0F2(4H20) and a green VOF2-(2H20), whereas at HF concentrations above 68.5% anhydrous VOF2 is stable.…”

New complexes were prepared from the reaction of vanadyl ion with malononitrile and succinonitrile. Both complexes were found to exhibit a decrease in C = N streatching frequency.The reaction of vanadyl ion with malononitrile ion gives a complex in which the C = N stretching frequency is increased. The increase or decrease is related to the type of bonding and to the difference in 7r-back bonding.
