摘要: A new series of homo- and heteropolynuclear copper(II) complexes N,N″-bis[1-biphenyl-2-hydroxyimino-2-(4-acetylanilino)-1-ethylidene]-diamines have been prepared characterized by different physical techniques. The starting point the research was reaction chloroacetyl chloride with biphenyl in presence aluminum chloride. 4-Biphenylhydroximoyl obtained reacting synthesized 4-(chloroacetyl)biphenyl alkyl nitrite. Substituted 4-(alkylaminoisonitrosoacetyl) (ketooxime) 4-biphenylhydroximoyl 4-aminoacetophenone EtOH. Homodi-, homotrinuclear heterodinuclear perchlorate tetradentate Schiff bases which possess N4 donor sets derived from condensation 4-(arylaminoisonitrosoacetyl)biphenyl diamine derivatives were characterized. Elemental analysis, FT-IR, ESR, molar conductivity, magnetic moment measurements thermal analyses studies utilized for investigation complexes. free ligands also 1H- 13C-NMR spectra. analyses, stoichiometric spectroscopic data metal indicated that metal:ligand ratio dinuclear found to be 2: 1 while this 3: 2 trinuclear ions are coordinated oxime imine nitrogen atoms. extraction abilities novel evaluated chloroform using several transition picrates such as Mn2+, Co2+, Ni2+, Cu2+, Zn2+, Pb2+, Cd2+, Hg2+. It has observed both show a high affinity Cu2+ ions.
