摘要：
Electronic paramagnetic resonance of paramagnetic Cu(II) complexes and nuclear magnetic resonance of diamagnetic Cu(I) complexes can give thermodynamic, kinetic and structural informations on these complexes. This methodology is examplified on two new ligands of N3S2 (L1) and N2S2(L2) type. EPR spectra of frozen solutions of Cu(II) complexes gave (from g// and A// parameters) structural data such as the tetrahedral deformation of the square-planar structure. H-1 NMR allowed determinations of stoechiometry and the corresponding stability constants. It gave also informations on ligand exchanges around Cu(I) cation.
