Abstract

Synthesis and spectral characterization of N,N'-Bis(2,4-dihydroxobenzylidene)1,2-diaminobenzene (DHDA) complexes with chosen f- and d-metal ions are described. Physico-chemical properties of a series of complexes: DHDA-La(NO(3))(3), DHDA-Eu(NO(3))(3). DHDA-Yb(NO(3))(3), DHDA-Cu(NO(3))(2), DHDA-Zn(NO(3))(2), DHDA-Co(NO(3))(2), were studied in methanol solution using UV-VIS, IR and fluorescence spectroscopy. Based on the absorption spectra the conditional stability constants of the metal complexes were determined.
