摘要：

The Schiff bases (L-1 and L-2) and their complexes [Cu(L)(2)] (L-1 = N-[(1)-1-(4-methylphenyl) ethylidene]benzolhydrazide and L-2 = N-[(1)-1-(2-methoxyphenyl)ethylidene] benzolhydrazide) have been prepared and characterized by elemental analysis, magnetic, and conductivity measurements. Crystal structure of the two complexes determined by single crystal X-ray analysis shows distorted square planar CuN2O2 coordination. Electron paramagnetic resonance spectra of these complexes in frozen DMSO show a signal at g ca 2. The trend in g-value (g(parallel to) > g(perpendicular to) > 2.0023) suggests that the unpaired electron on copper(II) has d(x2-y2) character. The superoxide dismutase and biological (antimicrobial) activities of these complexes have also been screened.
