摘要：

The complexes [Ni(Pyr(2)tetam-2H)]center dot 2H(2)O (1) (Pyr(2)tetam = (pyridoxyl)(2)-N-1,N-4-triethylenetetramine), [Fe(Pyr(2)tetam-2H)](ClO4)center dot H2O (2) and [Cu(Pyrtetam-H)](ClO4) (3) (Pyrtetam = pyridoxyl-N-1-triethylenetetramine) were obtained through one pot reactions of triethylenetetramine, pyridoxal chloridrate, triethylamine and the metal salts Ni(ClO4)(2)center dot 6H(2)O, Fe(ClO4)(2)center dot 6H(2)O and Cu(ClO4)(2)center dot 6H(2)O. In complexes 1 and 2 the metal centers present a distorted octahedral coordination, while complex 3 shows a square pyramidal configuration. The structures were characterized through X-ray diffractometry, IR and UV-Vis spectra. Cyclic voltammograms of the title compounds are also presented and discussed. (C) 2015 Elsevier B.V.
