| Abstract: | Four new complexes of Ni(II), Cu(II), Zn(II) and Co(III) with HL (HL= N,N'-di-beta-D-glucosylethylenediamine) have been synthesized in methanol solutions. The compositions of the complexes determined by elementary analysis are [Ni(HL)(H2O)2]2+ Cl2.CH3OH.2H2O, [Cu(HL)]2+ Cl2.CH3CH2OH.3H2O, [Zn(HL)]2+ Cl2.H2O and [Co(HL)(H2O)(OH)]2+ Cl2.CH3OH.2H2O respectively. They were also characterized by IR, UV and NMR spectra which show that complexes of Ni(II) and Co(III) have octahedral configuration, while complexes of Cu(II) and Zn(II) have tetralhedral configuration. The hydrolytic kinetics of p-Nitrophenyl picolinate(PNPP) catalyzed by these complexes in buffer solution was also studied spectrophotometrically. |
