The new 1-acetoacetanilide-4-phenyl-3-thiosemicarbazone (H2aapt) complexes; [M(Haapt)(AcO)(H2O)n](M = Co(II), n=1; M=Ni(II), n=2; M(II)=Cu, Cd, n=0), [M(Haapt)Cl(H2O)n](M(II)=Cu, Ru, n=2; M=Cd (II), n=1), [Cu(Haapt)2], [Pd(H2aapt)Cl2], [Ag(H2aapt)(H2O)2] NO3 and trans-[UO2(Haapt)2] are presented and studied by IR, 1H-NMR and electronic spectra, magnetic and thermal studies. The cyclic voltammetry was applied to study the electrochemical behavior of [Ru(Haapt)Cl(H2O)2] complex, which was found to be an efficient catalyst for the organic oxidation of primary alcohols, secondary alcohols, aldehydes and diols. The formation of complexes in solution was studied pH-metrically and the order of their stability constants (log k1 and log k2) were found to be Cu(II) > Ni(II) > Zn(II) > Cd(II) > Co(II) and Zn(II) > Cu(II) > Ni(II) >Cd(II)> Co(II), respectively.
