The reaction of VO(acac)2 with taurine o-vanillin schiff base ligand and ethylenediamine in CH3OH yields a binuclear vanadium compound [VO(μ2-O)(o-Vanillin-en)]2. The complex was characterized by IR spectroscopic method and X-ray crystal structure determination. It crystallizes in the triclinic space group P(-1) with a=0.898 67(19)nm, b=1.159 3(3) nm, c=1.200 0(3) nm, α=106.872(3)°,β=102.718(4)°, γ=94.905(3)° and Z=2. The interaction between the vanadium complex and calf thymus DNA has been investigated by UV-Vis absorption spectrophotometry and cyclic voltammetry. In UV-Vis spectrophotometry studies, the binding constant of the complex to DNA is 1.77×104 dm3· mol-1. CCDC: 658848.
