摘要:
Several new complexes of Sb(III) and Bi(III) with thiosemicarbazones of furfuraldehyde, thiophene-2-carbaldehyde, indol-3-carbaldehyde and pyridine-2-carbaldehyde have been prepared and characterized by elemental analysis, conductivity, molecular weight determination and IR, H-1- and C-13-NMR spectral studies. The ligands form complexes of the type MX3L[M = Sb(III) or Bi(II1); X = chloride; L = ligand] which are found to be non-electrolytes in DMF. Spectral data indicate that the thiosemicarbazones act as bidentate ligands through the azomethine nitrogen and sulphur.
