Spectrophotometric Study of Cobalt, Nickel, Copper, Zinc and Lead Complexes with Methylthymol Blue in Binary Water-Methanol Mixtures
The complexation reactions between methylthymol blue (MTB) and Co2+, Ni2+, Cu2+, Zn2+ and Pb2+ ions have been studied in different water-methanol mixtures at pH 4.45 and 25 °C by a spectrophotometric technique. The stepwise stability constants of the resulting 1:1 and 2:1 (metal ion to ligand) complexes were determined from the absorban...

Cobalt (II), Nickel (II), Zinc (II) and Manganese (II) Complexes of Pyridine-n-Carboxylic Acids with Hydrazine as a Ligand
Metal hydrazine, pyridine–2-carboxylate hydrates, pyridine–3-carboxylate hydrates, [ML(N2H4)0.5.H2O] where L = pyridine–2-carboxylic acid, pyridine–3-carboxylic acid and M = Co, Ni, Mn and Zn have been prepared and characterized by analytical, IR, UV-Vis and XRD Studies. Thermal decomposition of the compounds is studied from room temperature to 1200C by TG-DTA analysis. The compounds were found...
متن کاملSynthesis and Characterization of Nickel and Zinc Sulfide Ethylenediamine Complexes
In the present work, nickel and zinc sulfides ethylendiamine (N2H4C2H4) complexes were prepared in an autoclave at 180 C for 12 h. Transmission electron microscope (TEM) and X-ray powder diffraction were used to study the morphology of the two samples. The infrared absorption spectra were obtained and discussed in the range (200-4000 cm). New bands appeared at about 238,240 and 297 cm assigned ...
