Abstract

The reactions of 1 - chloro - 2 - nitro benzene with 2 - Amino thio phenol yield the 2 - ( ( nitro phenyl ) thio ) aniline and then 2 , 2' - thio dianiline of this compound was prepared . Also the symmetrical potentially pentadentate N 2 O 2 S Schiff base ligand 2 , 2' - ( ( ( thio bis (1 , 2 - phenylene ) ) bis ( azanilidene ) ) bis ( methenilidene ) ) diphenol ( H 2 L ) obtain by added salicylaldehyde . These compound have been characterized by FT - IR , 1 H NMR and Mass Spectrometry . Bi - nuclear Zn ( II ) complex of this ligand 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.
