Treść
Six complexes of various Mn(II) salts: MnBr2 center dot 4H(2)O (1), Mn(NO3)(2)center dot 4H(2)O (2), MnCl2 center dot 4H(2)O (3) with 2-(1-methyl-2-(pyridin-2-ylmethylene)hydrazinyl)benzo[d]oxazole L-A (complexes 1A-3A) and 2-(24(1H-imidazol-4-yl)methylene)-1-methylhydrazinyl)benzo[d]oxazole HLB (complexes 1B-3B) have been synthesited. All complexes were obtained in 1:1 stoichiometry. Their structures have been established through analytical and spectroscopic (ESI-MS, IR, H-1 NMR and microanalyses) methods as well as by X-ray structure determinations. In order to gain some insights into the electron-richness of studied systems, the electrochemical properties of ligands L-A and HLB and complexes 1A and 1B were investigated by cyclic voltammetry. Complexes 1A and 1B were chosen due to isostructurality what allows to the direct comparison of their behavior. The impact of pyridine and imidazole substituents on electrochemical behavior of synthesized systems was evaluated and showed that the presence of NH moiety in imidazole ring of HLB does not feasible the adsorption on the bare gold electrode.
