Tridentate hydrazido-hydrazones vanadium complexes : synthesis, properties and biological activity
Nine new vanadium complexes, with tridentate Schiff base ligand based on 3,5-di-tertbutyl-2-hydroxybenzaldehyde and different hydrazides, are described and characterized. The
X-ray crystal structure of complex 8 shows distorted octahedral geometry of vanadium, with
ONO ligand in equatorial position. The tridentate Schiff base ligand forms six membered and
five-membered chelate rings at the V(V) acceptor center, with the corresponding bite angles
being 82.97(9)藲 and 74.48(9)藲. The molecules are gathered by means of intermolecular OH...N hydrogen bond and layered by 蟺...蟺 interactions involving the pyridine and phenolate
rings. Such interactions expand the structure along the crystallographic a axis. The complexes
were characterized by the elemental analyses, IR, UV-Vis, EPR spectroscopy, cyclic
voltammetry, thermogravimetry and magnetic susceptibility measurements. The stabilization
role of co-ligands is discussed. The cytotoxicity versus HepG2 hepatocytes and inhibition of
human recombinant PTP1B was studied
