In the course of investigation of vanadium complexes, the title complex was prepared in aqueous solution using VOSO4 as starting reagent. The X-ray single crystal structure analysis indicates that the crystal belongs to P1 space group with cell parameters a=1.3523(6), b=1.4803(5), c=1.2587(7)nm, α=112.37(3), β=105.89(4), γ=83.75(4)°. The final R factor was converged to 0.068. The redox property of vanadium was studied in terms of the cyclic voltametric technique.
