LalAbstractNew dioxido-vanadium(V) complexes derived from hydrazone ligands have been synthesized in good yield. The complexes were characterized by elemental analysis, IR, UV–Visible and 1H NMR spectroscopies. The structure of both the complexes was established by Single Crystal X-ray crystallography. Complex 1 crystallized in monoclinic P21/n space group, with cell parameters a = 8.3725(5) Å, b = 15.0475(17) Å, c = 32.227(3) Å, α = 90°, β = 91.846(5)o, γ = 90°. Complex 2 crystallized in triclinic P-1 space group, a = 8.1871(7) Å, b = 11.2605(17) Å, c = 11.4031(18) Å, α = 105.961(14)°, β = 110.528(12)o and γ = 96.387(10)o. Both the complexes act as efficient catalyst which can catalyse the CH bond functionalization reaction.Graphical abstract
