Synthesis, Characterization and Theoretical Studies of a New Macroacyclic Schiff-Base Ligand Containing Piperazine Moiety and Related Mn(II), Cu(II), Ni(II) and Cd(II) Complexes
Four new [NiH2L](ClO4)2 (1), [CuH2L](ClO4)2 (2), [MnH2L](ClO4)2 (3) and [CdH2L](ClO4)2 (4), complexes were prepared by the reaction of a new Schiff base ligand and Cu(II), Ni(II), Mn (II) and Zn (II) metal ions in equemolar ratios. The ligand, H2L was synthesized by reaction of 1, 4- bis (2- formylphenyl) piperazine and ethanol amine and characterized with IR and 1H,13C NMR spectroscopy. All co...
