Abstract
Abstract Bis-chelates of Co(II), Ni(II),Cu(II) and Zn(II) with the thiol form of methyl n-hexyl ketone (MHKT) and methyl n-pentyl ketone (MPKT) thiosemicarbazones have been synthesised and characterised by analytical, conductivity, magnetic, infrared, electronic and electron spin resonance spectral studies. Based on analytical data the stoichiometry of the complexes has been found to be 1:2. The conductivity data show that all these complexes are non-electrolytes. The Co(II) complexes were found to have polymeric octahedral geometry. The Ni(II) and Zn(II) complexes are diamagnetic and were found to have square planar and tetrahedral geometry, respectively. Square planar geometry has also been suggested for the paramagnetic Cu(II) complexes.
