TL;DR: In this article, the infrared spectra of the three compounds {VO2F(AA) and {VOF3L2} showed two strong absorptions (in the 800-950 cm−1 region) which are likely to arise from vs and vas(VO2).

TL;DR: In this paper, a transduct of VO(acacac)2 with 2,2′-bipyridine via an oxide ligand was shown to have a cis configuration on the basis of the IR and Raman data.
Abstract: Diamagnetic dioxovanadium(V) complexes, VO2(β-dik)(phen or bpy), were prepared by the direct reactions of VO(β-dik)2 with 1,10-phenanthroline and 2,2′-bipyridine in dichloromethane under aerobic conditions as well as by two other methods. These compounds were concluded to have a cis configuration on the basis of the IR and Raman data. These complexes are solvolyzed to afford the di-μ-methoxo-or di-μ-hydroxo-divanadium(V) species, and are reduced by hydrogen bromide to the oxovanadium(IV) species in dichloromethane. In methanol instead of dichloromethane, VO(acac)2 reacted with 2,2′-bipyridine to produce a novel mixed-valence divanadium(IV, V) complex, V2O3(acac)3(bpy), which was revealed by the magnetic, spectral, and polarographic data to be a trans adduct of VO(acac)2 with VO2(acac)(bpy) via an oxide ligand.

TL;DR: In this article, the spectral properties of pyridine N-oxide and its metal complexes were investigated in the 2000-300 cm−1 region and the frequencies of the metal-ligand stretching, of the N-O stretching and of the CH out-of-plane bending vibrations were found to be closely correlated.
