Studies of Vanadyl(IV) Complexes with Schiff Bases of 2-Aminopyridine

摘要

A series of oxovanadium (IV) complexes with Schiff bases of 2-aminopyridine, i,e, 2-N-[p-dimethyl benzalidene] aminopyridine (PABAPy) and a thiosemicarbazone ligand, i,e,2-N-[acetylacetone] aminopyridine thiosemicarbazone (AcAyPyT) have been sjynthesized. On the basis of analytical and spectral studies complexes were found to have general composition VOX_2L_2 (X=Cl~-,Br~-,L=BAPy or PABAPy) and VOX_2 centre dotAcAcPyT(X=Cl~- or Br~-). V-atom is 5 or6 coordinated depending upon the anion present. NMR and antifungal studies of representative complexes have been done successfully.
