EPR of trigonal bipyramidal copper(II) complexes with tripod ligands

Mononuclear copper(ii) complexes with polypyridyl ligands: synthesis, characterization, DNA interactions/cleavages and in vitro cytotoxicity towards human cancer cells

“…The conditions for the EPR spectra for complexes [1] (ClO 4 ) 2 . These correspond to the g ⊥ value of the complexes and characteristics for the trigonal bipyramidal Cu(II) geometry (g ⊥ ∼ 2.1), 66 as can also be seen from the spectral shape of the EPR data (Fig. 4).…”
