Probing the synthetic protocols and coordination chemistry of oxido-, dioxido-, oxidoperoxido-vanadium and related complexes of higher nuclearity

Facile Synthesis of β-Tetracyano Vanadyl Porphyrin from Its Tetrabromo Analogue and Its Excellent Catalytic Activity for Bromination and Epoxidation Reactions

“…During the oxidation of X – , also observed in the functional model as well as in kinetics studies, the in situ generated oxido­(peroxido)­vanadium­(V) species allows nucleophilic attack of the halide ion, followed by the release of HOX/X 2 , which actually halogenate the substrates (Scheme ). − …”

Asymmetric dinuclear, hexanuclear and octanuclear oxovanadium citrates with triazolates: novel mixed-ligands and mixed-valence complexes

“…Based on the BVS calculation, 5a contains a mixed-valence [V IV O–(μ 2 -O α-alkoxy )–V V O] core, which is different from those of oxo-bridged dinuclear mixed-valence vanadium( iv / v ) complexes with the [V IV O–(μ 2 -O)–V V O] core. 18 Two K + ions are in contact with lattice water molecules and carboxy groups of citrates. Thus, three adjacent anionic clusters are held together through electrostatic attractions between K + and α-carboxy groups, leading to the formation of a three-dimensional (3D) layered structure (Fig.…”

Vanadium(v) complexes of mandelic acid

“…However, most of these compounds exhibit D 3h symmetry; or at least approximate C 3 axis passing through the (m 3 -O) atom. 40 In the case of anion [V 3 O 7 ((R)-mand)-((S)-mand)] 3À the geometry around the O atom is different and it lies in the symmetry plane of the C S symmetry.…”
