Polish Journal of Chemistry
1999 vol. 73 nr 2 263-269
EN The synthesis and characterization of (NH2RNH2)3CuCl2×H20 complexes, where R=(-CH2-)3 or (-CH(CH3)-CH2-) are reported. The complexes are octahedral. The ESR spectra of polycrystalline samples showed broad lines, which indicate spin-exchange interactions between copper(II) ions. In solution at 77K, t[...]

EN Copper(II) complexes of phenylhydrazoacetylacetone isonicotinoylhydrazone (PHAH) have been prepared and characterized by elemental and thermal analyses, conductance, magnetic moment, IR and UV-VIS spectra. The conductances indicate that the complexes are nonelectrolytes. In neutral solutions, mononu[...]
