摘要：
A new class of imidazole containing tripodal ligands has been synthesized containing from 0-3 imidazole pendants. Copper(II) complexes of the formulas [Cu(L)Cl]+ and [Cu(L)(1-MeIm)]2+ have been prepared and studied by UV-Vis and EPR spectroscopies and cyclic voltammetry. The X-ray crystal structures of [Cu(bipa)Cl]+ and [Cu(tmima)Cl]+ have been determined. Electrochemical and electronic spectral data suggest that the donor strengths of the tripods decrease in the following order: tpa > bpia > bipa > tmima. Results from EPR suggest that the complexes with tmima are more distorted than those of tpa. © 1990.
