Cis-[Co(en)2(1-Melm)2]Cl3, fac-[Co(dien)(ImH)3]X3 (X=Cl-, NO3-,ClO4-) and fac-[Co(dien)(1-Melm)3]Cl3 complexes were prepared and characterized by absorption, 1H NR, 13C NR and 59Co NMR spectra, where en, dien, imH and 1-elm denote ethylenediamine, diethylenetriamine, imidazole and 1-methylimidazole, respectively. Calculated coordination-induced shifts ranged from +0.62 to -0.03 pp for 1H and +7.11 to -1,19 ppm for 13C nuclei of imidazole ligands. The influence of imidazole methylation on 59Co NMR spectra was considered.
