摘要：

X-band e.s.r. and optical absorption spectra of the imidazolate bridged heterobimetallic complexes [(tren)Cu-E-Im-Zn-(tren)](ClO4)(3) and [(tren)Cu-E-Im-Ni-(tren)](ClO4)(3), where trentris(2-aminoethyl)amine, E-Im = 2-ethylimidazolate ion and the related mononuclear complexes [Cu(tren)](ClO4)(2) and [(tren)Cu-E-ImH)](ClO4)(2) have been described. Biological activities (superoxide dismutase and antimicrobial) have also been measured and compared with reported complexes. (C) 2003 Elsevier Science B.V. All rights reserved.
