Synthesis, characterization and thermal study of some new nano-structure zinc (II) halide/pseudohalide complexes

Nowadays nanostructure compounds are of interest because of notable properties with respect to bulk ones. Nanometer-size particles of metal coordination complexes enhance their physical and chemical properties that may be due to the large number of surface molecules when are compared with non-nanostructure compounds [1]. Schiff bases are the most widely utilized chelating ligands in the development of coordination chemistry. Schiff base compounds containing an imine group are usually formed by the condensation reaction between a primary amine and an active carbonyl. Because of the possible variety of the initial reactants for the synthesis of Schiff bases ligands, these compounds show a wide variety of chemical structures with different physicochemical properties [2]. In addition Schiff base metal complexes have been extensively investigated because of their potential applications in fields of science and technology such as catalysis area, medicine, optical industries, bioinorganic chemistry, polymer industries, and microbiological utilities [3]. In this work, we report synthesis, spectroscopic and thermal characterization of some new nano-structure zinc(II) coordination compounds of a bidendate Schiff base ligand entitled as (N1E,N6E)-N1,N6-bis((E)-3-phenylallylidene)hexane-1,6-diamine (Figure 1).The prepared compounds have been characterized by UV–visible, FT-SSIR, 1H-NMR and 13 C-NMR spectra. Moreover the zinc complexes were prepared in nanostructure size under ultrasonic conditions that confirmed by XRD, SEM, and TEM analyses.
