Studies of vanadyl(IV) complexes with Schiff bases of 2-aminopyridine

A series of oxovanadium(TV) complexes with Schiff bases of 2-aminopyridine, i.e., 2-N-[benzalidene] aminopyridine (BAPY), 2-N-[p-dimethyl benzalidene] aminopyridine (PABAPy) and a thiosemicarbazone ligand, i.e., 2-N-[acetylacetone] aminopyridine thiosemicarbazone (AcAyPyT) have been synthesized. On the basis of analytical and spectral studies complexes were found to have general composition VOX2L2 (X = Cl-, Br- L, = BAPy or PABAPy) and VOX2.AcAcPyT (X = Cl- or Br-). V-atom is 5 or 6 coordinated depending upon the anion present. NMR and antifungal studies of representative complexes have been done successfully.
