Synthesis and Characterization of Binuclear Zn(II) Complex of N2O2S Symmetrical Potentially Pentadentate Schiff Base Ligand

The reaction of 1-chloro-2-nitrobenzene with 2-aminothiophenol yield the 2-((nitrophenyl)thio)aniline and then 2,2 - thiodianiline of this compound was prepared. Then, the symmetrical potentially pentadentate N2O2S Schiff base ligand 2,2 - (((thiobis(1,2-phenylene))bis(azanilidene))bis(methenilidene))diphenol (H2L) was obtained by added salicylaldehyde. These compounds have been characterized by FT-IR, 1H NMR and Mass Spectrometry. Binuclear Zn(II) complex of H2L was prepared and structurally characterized by X-ray crystallography. The coordination geometry around Zn(II) is intermediate between trigonal bipyramidal and square pyramidal, τ = 0.54.
