E.s.r., magnetic, optical and biological (SOD and antimicrobial) studies of imidazolate bridged Cu(II)-Zn(II) and Cu(II)-Ni(II) complexes with tris(2-amino ethyl)amine as capping ligand: a plausible model for superoxide dismutase.

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