SULFUR-BONDED THALLOUS COMPLEXES OF THIOSEMICARBAZONES

An interesting series of some sulphur-bonded unusual bicoordinated tha llium(I) complexes of the type TIL (where L is the anion of a monobasi c bidentate thiosemicarbazone) has been obtained by the equimolar reac tions of thallous chloride with the sodium salt of the ligands (thiose micarbazones) derived from the condensation of heterocyclic aldehydes or ketones with thiosemicarbazide. The complexes have been characteriz ed by elemental analyses, conductance measurements, molecular weight d eterminations and electronic, IR, H-1 and C-13 NMR spectral studies.
