ABSTRACT:

Cobalt(II) complexes, Co(ATSC)2 Co(TTSC)2 CO(VTSC)2 and Co(FTSC)2 were prepared by reacting Cobalt(ll)acefate and bidenlate thiosemicarbazones derived from p-anlsaldehyde (ATSCH), p-tolualdehyde (TTSCH), p-vanillin (VTSCH). and 9-fluorenone (FTSCH) and were characterized by IR, uv-vlsble spectra, molar conductance1 magnetic moment and elemental analysis. The, observed spectral data on thiosemicarbonzones indicate thione form for the ligands and they act as anionic bidentate chelating agents. The coordination takes place through thiolato sulphur and azonmethine /imine nitrogen atoms. The tetrahedral flattened structures have been suggested for the cobalt(II) complexes under investigation.
