Six new copper(II) complexes of 2-hydroxyacetophenone-N(4)-phenyl semicarbazone have been synthesized and physico-chemically characterized. The tridentate character of the semicarbazone is inferred from IR spectra. Based on EPR studies, the spin Hamiltonian and bonding parameters have been calculated. The g values, calculated for all the complexes in frozen DMF, indicate the presence of the unpaired...
Seven new copper(II) complexes of 2-hydroxyacetophenone N(4)-substituted thiosemicarbazones (H 2 L) and bidentate polypyridyl compounds 2,2′-bipyridine and 1,10-phenanthroline (B) were prepared and characterized. The thiosemicarbazones bind to the metal as dianionic ONS donors (L 2− ) and yield compounds of the stochiometry [MLB]. The structure of the compound [Cu(L 4 )(2,2′-bipy)]...
