Equilibrium, Thermoanalytical and Spectroscopic Studies to Characterize Phytic Acid Complexes with Mn(II) and Co(II)
(Soc Brasileira Quimica, 2009-01-01)
Potentiometric studies were carried out to determine the binding degree of phytic acid with Co(II) and Mn(II) ions, in the absence of dioxygen. Equilibrium constants for all major complexes formed are reported, and the ...

Vibrational interpretation of the structure of Co(II), VO2+ and Pb(II) naphthalocyanine complexes
(1997)
The FT-IR and Raman spectra for the solid naphthalocyanine (H2Nc) and their Co(II), VO2+ and Pb(II) complexes were registered, and a band assignment was proposed. On this basis, the structure of the complexes was inferred: ...
Adsorption of Cu(II) and Co(II) complexes on a silica gel surface chemically modified with 2-mercaptoimidazole
(Springer, 1999-01-01)
The isotherms of adsorption of MeX2 (Me = Cu2+, Co2+; X = Cl-, Br-, ClO4-) by silica gel chemically modified with 2-mercaptoimidazole (SiMI) were studied in acetone and ethanol solutions, at 25 degrees C. Covalently attached ...
Surface vibrational study of macrocycle complexes: Co(II), Ni(II), Cu(II) and Zn(II) bis(phenylhydrazine)-1,10-phenanthroline
(Elsevier, 2002)
A complete assignment of the infrared spectra of the title macrocycles was carried out on the basis of well-documented references and a normal coordinate analysis based on a simplified molecular model. The structure of the ...
