Electronic (298.2 K) and ESR (298 and 77 K) spectra have been measured for Cu(O,CMe), solutions in pyridine derivative (L)\_solvent (S) binary mixtures (L = pyridine, 3chloropyridine, 2chloropyridine; S = n-hexane, n-heptane, cyclohexane, benzene, chlorobenzene, carbon tetrachloride, propylene carbo
The structures of three new Cu(II) complexes with pyridine carboxamide ligands (Me 2 bpb, 6-Me 2 -Mebpb, and 6-Me 2 -Me 2 bpb) have been determined. 6-Methyl-substituted pyridyl bpb ligands produced dimeric compounds with Cu(II) ions, and weak interactions between dimers can make even polymeric comp
## Abstract The pH‐dependent equilibria between Cu(II) and the potentially pentadentate ligands 4,7,10‐triazatridecane‐1,13‐diamine (__1__) and 1,9bis(2‐hydroxyphenyl)‐2,5,8‐triazanonane (**2**) have been studied in aq. solution at 298 K by EPR titration. Each ligand forms complexes CuLH~x~ (x=1,2,
