- Abstract
Complexes of Co(II), Ni(II), Cu(II), and Zn(II) containing N2S2 ligand have been synthesized from the template condensation reaction between 1,2-ethanedithiol, o-bromoaniline and dimethyl tin dichloride in 1:2:1 molar ratio. It resulted in the formation of new series of 11-membered N2S2-Tin macrocyclic complexes [MLX2Sn(CH3)2] (M=Co(II) or Zn(II); X=Cl or NO3); and [MLSn(CH3)2]X2 (M=Ni(II) or Cu(II); X=Cl or NO3). The complexes were characterized using techniques including elemental analyses, IR, 1H NMR, 119Sn NMR, EPR, electronic spectral studies, conductivity, and magnetic susceptibility measurements. The reducing power of the Co(II) and Cu(II) complexes have been checked and compared. The complexes derived from nickel and copper have been found to show square-planar geometry, while octahedral geometry is projected for the cobalt and zinc complexes.
