using a similar procedure i.e., treatment of [PPN]3[P3O9]·H2O (PPN = bis(triphenylphosphine)iminium) with the metal sources (CH3CN)2Mo(CO)2(η3-C3H5)Cl, MoO2Cl2(OSMe2)2, MoOCl3, VOF3, WOCl4, and WO2Cl2(CH3CN)2 to produce the corresponding salts, [PPN]2[(P3O9)Mo(CO)2(η3-C3H5)], [PPN]2[(P3O9)MoO2Cl], [PPN]2[(P3O9)MoOCl2], [PPN]2[(P3O9)VOF2]·2CH2Cl2, and [PPN]2[(P3O9)WO2Cl] in isolated yields of 78, 56, 75
Hydroxylammonium tetrafluoridooxidovanadate(V) has been prepared by reaction of (NH3OH)Cl and VOF3 in anhydrous HF solvent and characterised in the solid state by single-crystal X-ray diffraction and Raman spectroscopy. Colourless (NH3OH)[VOF4] crystallises in the monoclinic P21/n space group with a = 7.2349(2) Å, b = 5.0351(2) Å, c = 12.8322(4) Å, β = 94.843(3)°, V = 465.79(3) Å3 and Z = 4 at 150

An exploratory study of the synthesis of vanadium (oxy)fluorides (VOFs) using ionic liquids (ILs) and deep eutectic mixtures (DESs) as a solvent yielded 10 different materials. The previously reported chain type: (NH4)2VF5 (1), (NH4)2VOF4 (2), NH4VO3 (3) and (H2NH2(CH2)2NH2)VF5 (9) have been successfully produced for the first time using ILs as the reaction media. The monomeric (HNH2CH3)2VOF4(H2O)
Reactivity of VOF<sub>3</sub> with N-Heterocyclic Carbene and Imidazolium Fluoride: Analysis of Ligand–VOF<sub>3</sub> Bonding with Evidence of a Minute π Back-Donation of Fluoride
further scrutinized ligand bonding within [(LDipp)VOF3] (2) and related complexes, because, in this kind of complexes, a rather short distance between CNHC and cis-halogen atoms has spurred some discussion about the type of interactions between them. We provide evidence of a minute π back-bonding into NHC ligands, which is larger for chloride [(NHC)VOCl3] than fluoride [(NHC)VOF3] complexes, although the
