Abstract
Copper(II) complexes of phenylhydrazoacetylacetone isonicotinoylhydrazone ( PHAH) have been prepared and characterized by elemental and thermal analyse s, conductance, magnetic moment, IR and UV-VIS spectra. The conductances in dicate that the complexes are nonelectrolytes. In neutral solutions, mononu clear complexes, [Cu(H2L)Cl-2](2)H2O, [Cu(H2L)(2)Cl-2]H2O and [Cu(HL)Cl]H2O , have been obtained, however, in the presence of ammonia, the mononuclear complex [CuL.NH3](2) and binuclear complexes [Cu2LCl2]NH(3)5H(2)O and [Cu2L Cl(OH)]NH3 have been isolated.
