Abstract

The new lanthanum(III) and praseodymium(III) complexes of the general formula [LnCl(L)(H₂O)₂] (Ln = La^III or Pr ^III; H₂L = Schiff bases derived from 3-substituted-4- amino-5-hydrazino-1,2,4-triazoles and isatin) have been prepared. The complexes have been characterized by elemental analyses, molecular weight by FAB-mass, thermogravimetry, electrical conductance, magnetic moment and spectral (electronic, infrared, far-infrared, ¹H NMR and ¹³C NMR) data. The ligands and all prepared complexes were assayed for antifungal (Aspergillus niger and Helminthosporium oryzae) activities. The activities have been correlated with the structures of the complexes.
