Sažetak
The thiosemicarbazones are interesting primarly due to their biological activities with potential use in antibacterial, antiviral and antitumor treatment. Such compounds that have N, O and S donors are good metal-chelating agents [1]. In the last few years the structure of vanadium complexes is of particular interest because of their model character for biological function of vanadium [2]. Series of ligands and coresponding complexes with vanadium(V) ions was synthesized in order to investigate the above mentioned properties. Existance of thione– thiol tautomeric forms is the structural characteristic of the thiosemicarbazones derived from salicylaldehyde with the thione form dominating in the solid state. In the structuraly characterized complexes vanadium was found in the tetragonal- pyramidal environment with the oxo group in the apical position and thiosemicarbazone acting as a tridentate ligand. A molecule of solvent completes the coordination sphere of vanadium. [1] Cindrić M., Vrdoljak V., Strukan N., Kamenar B., Polyhedron, 2005, 24, 369-376.
