摘要：

The reactions of bis-(ethylenediamine)MX2, M(en)(2)X-2, bis-(1,3-propylenediamine)MX2, M(1,3-DAP)(2)X-2, and bis-(2,2-dimethyl-1,3-propylenediamine)MX2, M(2,2-DM-1,3-DAP)(2)X-2 complexes, [M = Cu-II or Ni-II and X = Cl- or ClO4-], after adjusting the pH values to 5, with 1,1-diacetyl-2,2'-biimidazole (Ac(2)BiIm) afforded octaazamacrocyclic Cu-II complexes (1-6) and Ni-II complexes (7-12). The solid complexes were characterized by elemental analysis, molar conductivities, IR, UV-vis, EPR, NMR and atomic absorption spectra, back titration, TGA and DTA. (C) 1997 Elsevier Science Ltd.
