Thermokinetic and spectral studies of niobium(V) complexes with 3-substituted-4-amino-5-mercapto-1,2,4-triazole Schiff bases

Metal complexes of niobium(V) with 3-substituted-4-amino-5-mercapto-1,2,4-triazole Schiff bases have been synthesized in dry chloroform under a nitrogen atmosphere. They were characterized by elemental analysis, molar conductance, electronic, infrared, 1H-NMR spectroscopy and thermal studies. Parame...
