Abstract
Cd (II) and Cr (III) Schiff base complexes were synthesized by template synthesis method. Cd (II) hydrated salts was reacted with Acetylene acetone and ethylenediami-ne in 1:2:1 molar ratios and Cr (III) anhydrous salt was reacted with Acetylene acetone, carbon disulfide and ethylenediamine in 1:1:2:2: molar ratios and N,N bis(acac)en Schiff base was synthesized by mixed en and acac in 1:2 molar ratios. Schiff base Cr (III) complex were coloured but Cd (II) complex was colourless. The product obtained Schiff base, Cr (III) and Cd (II) complexes were structurally investigated on the basis of conductance, magnetic susceptibility, IR, NMR etc. studies. The conductivity measurement of synthesized Cr (III) complex showed electrolyte, but Cd (II) complex was non-electrolyte and magnetic susceptibility showed Cr (III) complex was paramagnetic and Cd (II) was diamagnetic. At the last it is proposed that both the Cd (II) and Cr (III) complexes were showed octahedral geometry.
