A new oxovanadium(IV) complex, [VO(sal-val)(phen)]CH3OHH2O (sal-val=Schiff base derived from salicylaldehyde and L-valine, phen=1,10-phenanthroline), has been synthesized and characterized by elemental analysis, IR spectra, and single-crystal X-ray diffraction. This crystal belongs to monoclinic crystal system, C2/c space group with crystallographic data: a=28.031(4) angstrom, b=9.342(3) angstrom, c=19.198(4) angstrom, =99.425(2)degrees, and Z=8. The VIV was six-coordinate to form an octahedral geometry. In the crystal, intermolecular hydrogen bonding and stacking formed the 1-D network. DNA-binding properties of this oxovanadium(IV) complex with calf-thymus DNA (CT-DNA) were investigated using UV, fluorescence, and circular dichroism spectra. The complex can bind to CT-DNA via intercalation.
