The work presented in the Book entitled "Study on Metalloporphyrins" can be summarized in analytical and physical data; spectral data are compatible with the suggested structures. The complexes are colored, stable in air and insoluble in H2O, ethanol and non-polar solvents such as benzene. However, they dissolve in polar solvents such as DMF and DMSO. IR spectra of the complexes were recorded to confirm their structures. The assignments of the characteristic vibrational frequencies of the complexes were made by comparison with the vibrational frequencies of the free ligand. The ligand behaved...

The work presented in the Book entitled "Stability constants of metal complexes" can be summarized as below. The practical proton-ligand and metal-ligand stability constants were determined by Calvin-Bjerrum titration technique using nitric acid and constant ionic strength was maintained with sodium nitrate. It was pointed out by Irving and Rossotti, that it is neither necessary to convert pH meter reading "B" to stoichiometric hydrogen ion concentration nor to know the stoichiometric concentration of the neutral salt added to maintain constant ionic strength. The method is valid both in...

Summarizes the preparation and structure characterization of various thiosemicarbazones attached Quinoline aldehyde as well as their metal complexes. Synthesized ligands and metal complexes were characterized by different technique like mass, IR, 1H NMR, 13C NMR, UV-Visible spectroscopy as well as elemental analysis. In the elemental analysis of the synthesized compound both calculated and found percentages of elements are matched so elemental analysis confirms the structure of the thiosemicarbazone. Mass spectral data confirm the structure of the ligand as indicated by the molecular ion peak...
