Synthesis and spectroscopic studies of Sb(III) and Bi(III) complexes of semicarbazones

摘要

New complexes of Sb(III) and Bi(III) with semicarbazones of the general formulae SbCl3Land BiCl3L(whereL=semicarbazones) have been prepared and characterized by IR,1H- and13C-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 inDMFsolution. The molecular weight determinations indicate that the compounds are monomeric.
