SYNTHESIS AND SPECTROSCOPIC STUDIES OF SB(III) AND BI(III) COMPLEXES OF SEMICARBAZONES

New complexes of Sb(III) and Bi(III) with semicarbazones of the general formulae SbCl3L and BiCl3L (where L = semicarbazones) have been prepared and characterized by IR, H-1- and C-13-NMR spectral measurements. The results of the spectroscopic studies indicate that the semicarbazone ligands act as bidentate in all the complexes. All complexes are non-electrolytes in DMF solution. The molecular weight determinations indicate that the compounds are monomeric.
